DAASE: Dynamic Adaptive Automated Software Engineering

Lead Research Organisation: University College London
Department Name: Computer Science

Abstract

Current software development processes are expensive, laborious and error prone. They achieve adaptivity at only a glacial pace, largely through enormous human effort, forcing highly skilled engineers to waste significant time adapting many tedious implementation details. Often, the resulting software is equally inflexible, forcing users to also rely on their innate human adaptivity to find "workarounds". As the letters of support from the DAASE industrial partners demonstrate, this creates a pressing need for greater automation and adaptivity.


Suppose we automate large parts of the development process using computational search. Requirements engineering, project planning and testing now become unified into a single automated activity. As requirements change, the project plans and associated tests are adapted to best suit the changes. Now suppose we further embed this adaptivity within the software product itself. Smaller changes to the operating environment can now be handled automatically. Feedback from the operating environment to the development process will also speed adaption of both the software product and process to much larger changes that cannot be handled by such in-situ adaptation.


This is the new approach to software engineering DAASE seeks to create. It places computational search at the heart of the processes and products it creates and embeds adaptivity into both. DAASE will also create an array of new processes, methods, techniques and tools for a new kind of software engineering, radically transforming the theory and practice of software engineering. DAASE will develop a hyper-heuristic approach to adaptive automation. A hyper-heuristic is a methodology for selecting or generating heuristics. Most heuristic methods in the literature operate on a search space of potential solutions to a particular problem. However, a hyper-heuristic operates on a search space of heuristics.

We do not underestimate the challenges this research agenda poses. However, we believe we have the team, partners and programme plan that will achieve the ambitious aim. DAASE integrates two teams of researchers from the Operational Research and Search Based Software Engineering communities. Both groups of researchers are widely regarded as world leading, having pioneered the fields of Hyper-Heuristics and Search Based Software Engineering (SBSE); the two key fields that DAASE brings together.

Planned Impact

Training: The experience that our (many) early career researchers will obtain will be highly valuable and transferable: optimisation is a generic concern, widely applicable to many engineering problems (not merely those found in software engineering). DAASE will facilitate a wide-ranging and comprehensive programme of research training that will encompass exposure to different research communities and a wide range of different industrial environments. We plan internal research training, industrial secondments, international outreach visits and cross-site collaboration to maximise DAASE's potential to offer our team the best possible opportunities to develop their career, skills and expertise.

General Public: We plan to reach the public through direct engagement activities, print and broadcast media and by creating smart phone and social media apps that inform and explain. This activity will be headed up by Drs. Sue Black and Peter Bentley, both of whom have outstanding track records of media engagement and advocacy of science and engineering. The section on `Advocacy for Engineering and the Physical Sciences' in the case for support explains this in more detail.

SMEs: DAASE has the potential to directly impact hundreds of SMEs. This is why UCL has committed to appoint (and fund) the full-time DAASE Business Development Manager to ensure that the project collaborates with an order of magnitude more SMEs than could otherwise be possible.

DAASE will benefit from significant and sustained support and interaction with a large set of industrial partners, including,
IBM and Microsoft (representing the software industry), BT, Ericsson and Motorola (representing the telecoms sector) and ABB, Berner&Mattner and Honda (representing the manufacturing sector). We also set out more detailed plans in the "Pathways to Impact" document, explaining how we shall use these DAASE partners to experiments with our ideas, evaluate new techniques, pose industrial challenges and to provide support and consultancy concerning the industrial application of DAASE techniques. Through this interaction with leaders in the field DAASE will seek to impact the immediate industrial partners. The Business Development Manager will ensure that DAASE also reaches out to and impacts a far wider pool of SMEs.
 
Title Tunnelling Crossover Networks for the Asymmetric TSP 
Description Local optima networks are a compact representation of fitness landscapes that can be used for analysis and visualisation. This paper provides the first analysis of the Asymmetric Travelling Salesman Problem using local optima networks. These are generated by sampling the search space by recording the progress of an existing evolutionary algorithm based on the Generalised Asymmetric Partition Crossover. They are compared to networks sampled through the Chained Lin-Kernighan heuristic across 25 instances. Structural differences and similarities are identified, as well as examples where crossover smooths the landscape.

Description The DAASE Project has not only fundamentally changed the science of software engineering, but also the practice. The research has had a direct impact on over 2 billion people worldwide, who use software systems for communications, community building and social networking, which were tested and optimized using the project's research. The project developed techniques to automatically design test cases, to explore and find bugs in software systems, and also techniques for improving software, to enhance its performance and remove problems identified by the testing. This work has been deployed by several companies including KLM and Facebook.

The DAASE project has also fundamentally shifted the locus of research within the scientific community. The project ran from 2012 to 2019, and during that time the number of research papers and active researchers in search based software engineering has grown exponentially. Recent publications [1,2] that survey the area attest to both the growth in interest and activity in the scientific community, and the seminal role played by the DAASE project and it's researchers, many of whom have gone on to promotions and/or industrial secondments. DAASE researchers won seven best/distinguished paper awards. Its research won five Hummies (http://www.human-competitive.org/awards): one gold, two silver and two bronze. Its research also won two SSBSE Challenge tracks. The DAASE project co-PI, Mark Harman, won two distinguished scientific awards for his work on DAASE: IEEE Harlan Mills 2019 and ACM Outstanding Research 2019. DAASE members have given keynotes about DAASE at all the leading international conferences in the area.

Description DAASE work has been deployed by several companies, including KLM and Facebook. The deployment at Facebook was made possible by the acquisition by the company founded by several of the key researchers from the project, including the principal investigator, Professor Mark Harman, and PhD student Ke Mao and an Associate Professor, Yue Jia. This team, acquired by Facebook, went on to work with others at Facebook, based in London, to deploy the Sapienz system, which automatically designs test cases. The DAASE PhD student, Alexandru Marginean, subsequently worked with them to deploy automated program improvement. Through these deployments, the research work has directly reached and touched the lives of over two billion people worldwide. Through this acquisition, DAASE research has been deployed into Facebook production systems, and software testing processes, running continuously to test software systems of many millions of lines of code. This deployment is a testament to the industrial scalability of the scientific work, its profound and wide-reaching impact; Over 1.5 billion people use Facebook products every day (2.7 billion per month), with the result that their lives have been directly affected by this research project. This first was reported by Facebook in August 2018, and the blog post reporting it went immediately viral, being picked up by SD Times, CNET, SiliconANGLE (further picked up by SlashDot), Startup World, The Register, TechCrunch (further picked up by the Verge), ZDNet, The Next Web (further picked up by Wheaton Business Journal), Fossbytes, and JAXenter, already seeing recruitment enquiries as a result. Following a further press event, Sapienz was also picked up and reported on by Forbes and subsequently,byTom'sGuide,TechworldfromIDG,VentureBeat,andV ersion2. Additional Real World Impact ? KLM uses DAASE technology for airline schedules; ? Automatically evolved changes to BarraCUDA have been deployed and used as open source http://seqbarracuda.sourceforge.net/; ?

Type Of Material Improvements to research infrastructure 
Provided To Others? No  
Impact Although the triangle program is small, the number of possible triangle programs is huge. We have fully explored a regular subset of it. We reduced the size of its search space by considering only potential improvements to the existing code made by replacing its comparisons and by restricting the comparator mutations. This enabled us to analyse a systematic subset of the whole improvement fitness landscape. Solutions in the subset will still be solutions in the full problem. There are many solutions all of which are readily found by first order schema analysis. Suggesting the program fitness landscape is not as difficult to search as is often assumed.

Title POSIT 
Description This a project to simultaneously provide language ID tags and Part-Of-Speech or compiler tags (which are taken from CLANG compilations of C and C++ code). The corpus is either code with comments annotated with CLANG compiler information and universal PoS tags for English, or StackOverflow. For StackOverflow we start from the data dump (which can be found here), and use a frequency based heuristic to annotate code snippets. The frequency data is made available under ./data/corpora/SO/frequency_map.json. To generate training data from StackOverflow, please use the scripts under ./src/preprocessor together with the Posts.xml file from the data dump linked above. Our model is a BiLSTM neural network with a Linear CRF and Viterbi decode to go from LSTM state to tags or language IDs. We use the same LSTM network and change only the CRF on top for the two tasks. We linearly combine the two objectives in the loss with a slightly smaller weight given to language IDs. We do not condition Tag output on language IDs in this version of the model.

Results and Impact Co-Chaired by Dr David R White and Dr Justyna Petke

The growth in GI echoes a wider trend in research on the use of evolutionary and genetic search in optimising aspects of software engineering. For example, since 2002 there has been a track on Search Based Software Engineering at GECCO. There exists the dedicated SSBSE conference, and we now see the inauguration of regional conferences and workshops featuring or even dedicated to SBSE (in Brazil, China and recently the USA). In 2015 the inaugural Genetic Improvement Workshop was held in conjunction with GECCO. The workshop was a tremendous success.

Genetic Improvement is one of the most exciting and growing applications of evolutionary search. Including "to appear", since 2000, there have been more than 70 papers in this area and interest is growing. GI research has won three GECCO Human Competitive Awards (Gold, Silver and Bronze) and two best papers, including at the International Conference on Software Engineering and GECCO. Furthermore, a special issue on Genetic Improvement in the Genetic Programming and Evolvable Machines journal is due to appear in the coming months.

Whilst SBSE has traditionally been applied to software engineering problems there has been great interest in using it, particularly genetic programming, on software itself.

Genetic Improvement (GI) uses computational search to improve software while retaining its partial functionality. The technique was first applied to parallelise programs and optimise and find compromises between non-functional properties of software, such as execution time and power consumption. This work led on to automated bug fixing in commercial software. More recently, it has been shown that GP can use human written software as a feed stock for GP and is able to evolve mutant software dedicated to solving particular problems. Another interesting area is grow and graft GP, where software is incubated outside its target human written code and subsequently grafted into it via GP.

Geographic Reach International
Primary Audience Postgraduate students
Results and Impact Estimates for the amount of global energy consumed by computation may very, but no commentator doubts its increase, with serious environmental implications. Users are also frustrated, all too aware of the computational limitations of inadequate battery life. Indeed, the largest component in many mobile devices is the battery. However, despite these pressing environmental and user needs, there remains a lack of work on computational energy testing and optimisation. The 39th CREST Open Workshop (COW) workshop will bring together those working on testing and optimisation with those working on computational energy measurement and its applications to investigate and develop computational energy testing and optimisation research and practice. Funding for the workshop is provided by the EPSRC projects GISMO (http://www0.cs.ucl.ac.uk/staff/W.Langdon/gismo/) and DAASE (http://daase.cs.ucl.ac.uk).

Primary Audience Postgraduate students
Results and Impact Genetic Improvement (GI) aims to find improved versions of existing programs that retain some partial semantics of the original (and possibly some of its syntax too). GI has been used to improve many system aspects such as its correctness (through bug fixing) and resource consumption such as time, memory and energy. It has also been used for other kinds of improvement such as specialising and porting. Many and varied techniques have proved successful at improving programs, such as loop perforation, genetic programming, guided random search, transplantation and constraint-based synthesis. This workshop will bring together researchers working on Search Based Software Engineering (SBSE), Program Synthesis, Genetic Programming, Program Analysis and Manipulation. We will explore the possible applications, development of techniques, evaluation and theory. Funding for the workshop is provided by the EPSRC projects DAASE (http://daase.cs.ucl.ac.uk) and GGGP.

Primary Audience Postgraduate students
Results and Impact How can we automatically generate algorithms on demand? While this was one of the original aims of Machine Learning and Artificial Intelligence in the early 1950s, and more recently Genetic Programming in the early 1990s, existing techniques have fallen-short of this elusive goal. This workshop will outline a number of steps in the right direction on the path to achieving this goal. In particular, this workshop will focus on the burgeoning field of hyper-heuristics which are meta-heuristics applied to a space of algorithms; i.e., any method of sampling a set of candidate algorithms. Genetic Programming has most famously been employed to this end, but random search and iterative hill-climbing have both also successfully been employed to automatically design novel (components of) algorithms.

The main objective of this workshop is to discuss hyper-heuristics employing evolutionary computation methods for generating algorithms. These methods have the advantage of producing solutions that are applicable to any instance of a problem domain, instead of a solution specifically produced to a single instance of the problem. The areas of application of these methods include, for instance, data mining, machine learning, and optimization.

Results and Impact The 6th International Workshop on Genetic Improvement @ ICSE 2019, 28th May 2019 Genetic Improvement is the application of evolutionary and search-based optimisation methods to the improvement of existing software. For example, it may be used to automate the process of bug-fixing or execution time optimisation. As academics in the field, we run the workshop to offer an opportunity for researchers to disseminate work, but most importantly to meet and discuss with other GI researchers. So far we had 5 editions of the workshop, four co-located with GECCO (in 2015, 2016, 2017 and 2018) and one with ICSE 2018. Since 2009 there have been four human competitive awards for work in GI (two Gold, one Silver and one Bronze) presented at GECCO and three best papers, including at the International Conference on Software Engineering and International Symposium on Software Testing and Analysis.

Results and Impact Search-Based Software Engineering (SBSE) is the application of search algorithms to the solution of software engineering tasks. We invited papers that address problems in the software engineering domain through the use of heuristic search techniques. We particularly encouraged papers demonstrating novel search strategies or the application of SBSE techniques to new problems in software engineering.
Self-* search techniques incorporate ideas from adaptation and machine learning. The goal is to reduce the role of the human expert in the process of designing search algorithms, and to produce more generally applicable and robust methods. This will contribute to the long-standing challenge of self-adaptive software systems.

Form Of Engagement Activity Participation in an activity, workshop or similar

Geographic Reach International
Primary Audience Postgraduate students
Results and Impact Recent work on Genetic Improvement (GI) has covered automatic bug repair and improving both functional and non-functional properties of existing software code.

Non-functional improvements have included radical speeds ups and (particularly for low resource computational motes and mobile computing) reducing energy consumption, and memory footprint.

In addition to automatic bug fixing, functional improvements have included growing and grafting in new functionality, automatic porting to new hardware (often parallel hardware such as GPU and SSE vector instructions), automatic tuning and transplanting functionality from existing often open source repositories like GitHub.

These are exciting times but as highlighted by the recent Dagstuhl Seminar on Automated Program Repair (17022), there is a risk that lessons learnt in one area will only be exploited by that area. Therefore this Dagstuhl Seminar will draw participants from all corners of GI to contribute their thoughts on experiences, tools, datasets and benchmarks, validation, theoretical analysis and the ways forward.

What will programming look like in ten years' time? How will GI in 2018 be thought of in 2038 or in 2050?

The seminar will focus on various genetic improvement approaches and related areas where software has been reused for purpose of automated software improvement. The proposed topics of discussion include:

software mutational robustness
program repair
non-functional software property improvement
search-based approaches for software improvement
data mining for GI

Search-based Software Engineering (SBSE) is a research area focused on the formulation of software engineering problems as search problems, and the subsequent use of complex heuristic techniques to attain optimal solutions to such problems. A wealth of engineering challenges - from test generation, to design refactoring, to process organization - can be solved efficiently through the application of automated optimization techniques. SBSE is a growing field - sitting at the crossroads between AI, machine learning, and software engineering - and SBSE techniques have begun to attain human-competitive results.
The Symposium on Search-Based Software Engineering is a venue dedicated to the SBSE research field. The 11th symposium will be held this year in Talinn, Estonia, co-located with the 27th ACM Joint European Software Engineering Conference and Symposium on the Foundations of Software Engineering. We invite the submission of high quality papers describing novel and original work in all areas of SBSE including, but not limited to, applications of SBSE to novel problems, theoretical analyses of search algorithms for software engineering, rigorous empirical evaluations of SBSE techniques, and reports of industrial experiences.

Abstract:

Genetic Improvement (GI) uses modern search and optimisation
techniques, principally Genetic Programming (GP), to optimise
existing programs. I will start with a very brief introduction
to GP, particularly its use in evolving optimisation benchmarks,
hyper-heuristics, network protocols, composing web services,
cache management strategies, specialising hashing and malloc,
redundant programming and automatic bugfixing. There are many
ways to balance requirements against resources (such as CPU,
memory and energy consumption), but we cannot try them all. Also
the easiest program to write (and maintain) may not be the most
accurate or give the best trade-off between speed and
quality. Then again the Pareto optimal tradeoff may be different
on each hardware platform and it may change with time. Potentially
GI could automatically customise apps for different users, even
for different times of the day for the same user.

Mostly I will concentrate on examples, such as were GI
automatically customised existing programs to give considerable
speed ups by evolving a new version of the program tailored to
special cases.

Bill Langdon - UCL
H170 15:30-16:30

Genetic Improvement (GI) uses modern search based software engineering

(SBSE) techniques such as Genetic Programming (GP), to optimise

existing programs.? I plan to start with an introduction to genetic

programming. Then give very brief descriptions of early GP work on

evolving software from scratch and recent work on automatic bug fixing.



Part of the motivation for GI is that customising software for

different users, different hardware, different trade-offs between

resources consumption (eg memory, speed, battery life) and quality,

is at least as difficult and labour intensive as many other programming

tasks and yet (we shall see) is at least partly automatable.



Mostly I will concentrate on examples, such as given by the paper

doi:10.1109/TEVC.2013.2281544 of the same name as the talk. Here GI

automatically customised existing programs to give considerable speed

ups with little lost in accuracy by evolving a new version of the

program tailored to special cases.

Results and Impact In the past ten years there has been a dramatic increase in work on Search-Based Software Engineering (SBSE), an approach to software engineering in which search-based optimisation algorithms are used to address problems. The approach is attractive because it offers a suite of adaptive automated and semi-automated solutions in situations typified by large complex problem spaces with multiple competing and conflicting objectives. SBSE has been applied to a number of software engineering activities, right across the life-cycle from requirements engineering, project planning and cost estimation through testing, to automated maintenance, service-oriented software engineering, compiler optimisation and quality assessment.

With this special session, we are providing an opportunity to showcase recent breakthroughs in this field.

Scope and Topics

We invite submissions on any aspect of SBSE, including, but not limited to, theoretical results and interesting new applications. The suggested topics cover the entire range of functional and non-functional properties:

bandwidth minimisation
latency minimisation
fitness optimisation
energy optimisation
software specialisation
memory optimisation
software transplantation
bug fixing
multi-objective SE optimisation

Results and Impact BarraCUDA is a Bioinformatics tool which looks up in a reference genome short noisy DNA sequences produced by the billion by next generation sequencing tools. It is a port of the BWA algorithm by six co-authors who included both experts on CUDA and experts in Bioinformatics, especially BWA and the BWT compression algorithm. BarraCUDA is open source CUDA code and is available from SourceForge. The existing code was improved by a combination of manual changes and automatic genetic evolution. The genetically improved code has been incorporated and has been available from SourceForge for a year.

As with all implementations of BWT, speed depends upon the length of the DNA reads. For shorter reads a single lowly GT 730 (£50) can be faster than BWA. The GI version of BarraCUDA is up to three times faster than the earlier version of BarraCUDA. The new version has been adopted by Lab7 and IBM (including for Power8).

Results and Impact Deep Learning for Programming Language Type Inference
On Friday, November 16th, as part of source{d} paper reading club [1], we are going to talk about a paper that was recently published at FSE'18: Deep Learning Type Inference [2].

ABSTRACT
Dynamically typed languages such as JavaScript and Python are
increasingly popular, yet static typing has not been totally eclipsed:
Python now supports type annotations and languages like TypeScript
offer a middle-ground for JavaScript: a strict superset of
JavaScript, to which it transpiles, coupled with a type system that
permits partially typed programs. However, static typing has a cost:
adding annotations, reading the added syntax, and wrestling with
the type system to fix type errors. Type inference can ease the
transition to more statically typed code and unlock the benefits of
richer compile-time information, but is limited in languages like
JavaScript as it cannot soundly handle duck-typing or runtime evaluation
via eval. We propose DeepTyper, a deep learning model
that understands which types naturally occur in certain contexts
and relations and can provide type suggestions, which can often
be verified by the type checker, even if it could not infer the type
initially.

Description The 26th CREST Open Workshop - Dynamic Adaptive Automated Search Based Software Engineering (joint DAASE/COW workshop) 
Form Of Engagement Activity Participation in an activity, workshop or similar
Part Of Official Scheme? No
Geographic Reach International
Primary Audience Postgraduate students
Results and Impact Current software development processes are expensive, laborious and error prone. They achieve adaptivity at only a glacial pace, largely through enormous human effort, forcing highly skilled engineers to waste significant time adapting many tedious implementation details. Often, the resulting software is equally inflexible, forcing users to also rely on their innate human adaptivity to find "workarounds". Yet software is one of the most inherently flexible engineering materials with which we have worked. Something is clearly wrong. This workshop will consider ways in which the theory, methods, practice and techniques associated with Search Based Software Engineering (SBSE) can be used to enhance software adaptivity. The workshop is partly sponsored by the EPSRC programme grant DAASE: http://daase.cs.ucl.ac.uk/.

Results and Impact App stores provide a rich source of information for software engineering research: It is, of course, possible to extract technical information as with other software systems. However, we can also readily obtain information relating to customer reviews, pricing and popularity. Never before in history of software engineering has so much information been available concerning so many, and so disparate, facets of software systems. Increasingly, the users of apps and app stores are relying on the software they provide for highly nontrivial activities, making app store analysis a pressing concern. This workshop will bring together software engineers to discuss and develop the emerging research agenda in App Store Analysis.

Form Of Engagement Activity Participation in an activity, workshop or similar
Part Of Official Scheme? No
Geographic Reach International
Primary Audience Postgraduate students
Results and Impact Search Based Software Engineering (SBSE) has proved extremely attractive to software engineers, because it handles messy conflicting multi-objective problems and copes well with noise and with partial and contradictory information. Although SBSE has proved very widely applicable and generalisable, many software engineers now find themselves bewildered by the enormous variety of potential computational search algorithms available to them. For many software engineering problems, generalist algorithms that perform acceptably well (across a wide range of problem instances) would be considerably preferable to a set of specific algorithms, each of which has to be carefully selected and tuned to the particular problem in hand, even if such careful tuning could outperform the generalist. Hyper-heuristics offer such a generalist solution, able to learn and adapt to the problem in hand, and therefore they have become increasingly attractive to software engineers. This workshop will bring together researchers working on hyper-heuristics and SBSE, seeking to stimulate wider and deeper collaboration, and to map out an agenda for Hyper-Heuristic Software Engineering. Funding for the workshop is provided by the EPSRC project DAASE (http://daase.cs.ucl.ac.uk).

Results and Impact "Correlation is not causation" is a widely-observed scientific maxim. Unfortunately, this observation is highly correlated with hypersensitive scientific cautiousness; it may even have caused it in some cases. We are naturally reticent to speculate about cause, but in order to more deeply understand many phenomena, including those of importance to software engineers, we need techniques that allow us to talk about causes. This CREST Open Workshop will be a tutorial on Causal Impact Analysis, featuring a one-day foundational tutorial from Kay Brodersen (Google Inc. and ETH), who introduced time series models of causal impact, followed by a shorter quarter-day tutorial by William Martin (CREST UCL) on applications of Brodersen's approach to Windows Phone Store. The two tutorials will be followed by an open discussion on applications of causal impact analysis to software engineering problems.

Results and Impact It has been widely observed that software engineers often implement 'not quite right' solutions to gain value in form of fast delivery and prototyping. Moreover, it is believed that engineers resist attempts to change systems to avoid disruption and other costs this might incur, thereby building up a set of delayed interventions known as technical debt. This poses significant challenges to research and practice, including measuring and understanding technical debt, managing and ameliorating its effects, and providing automated and semi automated support to software engineers. This workshop will focus on software architecture and design, and the role it has to play in addressing these issues of technical debt. It will draw together experts in software architecture, measuring and understanding technical debt, and the provision of automated and semi automated support.

Results and Impact Genetic Improvement (GI) uses automated search to find improved versions of existing software. GI has been used to improve many system aspects such as its correctness (through bug fixing) and resource consumption such as time, memory and energy. It has also been used for other kinds of improvement such as specialising and porting. Many and varied techniques have proved successful at improving programs, such as loop perforation, genetic programming, guided random search, transplantation and constraint-based synthesis. This workshop will bring together researchers working on search based software engineering, program synthesis, genetic programming, program analysis, data mining and machine learning. We will explore the possible applications and connections between the various fields that will hopefully lead to development of new GI techniques for automated software improvement.

Primary Audience Postgraduate students
Results and Impact Overview:

Software is bimodal: it interlinks two channels, an algorithmic channel aimed at devices and a natural language channel aimed at developers. Most research has focused on one channel or the other, not their interplay. Simultaneously considering both channels promises a new source of constraints for improving program analysis and software engineering tools. For example, names in program text can be exploited to refine a type lattice. The CREST Open Workshop on PL and NLP will explore how to identify and exploit these cross-channel connections.

Geographic Reach International
Primary Audience Postgraduate students
Results and Impact Code Review has become a widely accepted approach to continuously ensure the quality of software undergoing changes. It is used both in industry and open source software development and has transformed over the past decade to a change-focused process that is deeply integrated with continuous integration and inspection. While continuous integration and inspection is a fully automated process to ensure quality, code review relies on humans. New approaches feed the results of static and dynamic analysis during continuous integration to reviewers in order to support them in their reviewing task. Moreover, the additional information available through code review repositories has enabled researchers to study day-to-day software development, for example, by studying the motivation and discussions on proposed changes.

This workshop will bring together world leading researchers and practitioners interested in code review and continuous inspection/integration. The aim is to discuss the latest achievements in analysing and understanding commits and code reviews, and how commit and code review repositories help to analyse general software engineering problems.

Geographic Reach International
Primary Audience Postgraduate students
Results and Impact This workshop seeks to bring together researchers working on Automated Repair, Empirical Software Engineering, Genetic Improvement, Program Analysis & Synthesis, and Software Testing & Transplantation explore the possibility that automated scientific experimentation could and should be part of automated program improvement: Whereas human engineers are too time-constrained to perform extensive systematic experimentation that documents and justifies their code changes, the machine is comparatively unconstrained.

Advances in automated program improvement suggest an exciting future in which automated techniques combine with human insights and domain expertise to collaborate on the challenge of improving software systems. In this workshop we address the research question: How can we best combine and exploit the machines' ability to automatically navigate large improvement search spaces with human insight, decision making and domain expertise?

Much of the tech sector deploys through continuous integration, underpinned by modern code review, thereby providing a readily re-targetable infrastructure for machine-human collaboration on code change. The workshop seeks to accelerate industrial deployment by exploring the requirements for code improvement techniques that automatically provide systematic, well-documented, empirical evidence to the human code reviewer that supports the suggested program improvements they have found.

Results and Impact Software analysis tools typically focus on a single programming language but modern software systems are typically comprised of elements written in many different programming languages. As such, techniques that can address multiple programming languages are ever more important and can provide software engineers with better ways to undertake software development, maintenance, and evolution. Researchers also benefit from being able to study software systems in their entirety rather than being restricted to those facets for which tools and techniques are available.

This workshop will bring together world-leading researchers and practitioners interested in multi/mixed language software analysis to discuss the latest achievements in supporting, analysing, and understanding multi-language analysis and how this can help support software engineering processes.

Primary Audience Professional Practitioners
Results and Impact Overview:

DAASE has advanced the state of the art in numerous directions: novel, principled technique for handling class imbalance, optimising energy consumption, automated program repair, automatically generating product roadmaps, to name a few.

DAASE has achieved breakthroughs, including automated software transplantation, the first approach for transplanting code that dynamically adapts it for a new context, and a human-competitive multi-objective software effort estimator that balances accuracy against variance, both of which won Hummies at GECCO. DAASE has pioneered a new field of research called genetic improvement and produced award-winning work on fitness landscape analysis and visualisation.

DAASE has spawned a number of start-ups, most notably Sapienz which Facebook acquired and which now tests and automatically repairs code at Internet scale. Heathrow's plane scheduling now relies on a bespoke optimisation algorithm devised by DAASE researchers. Automated software repair using genetic improvement is also now a part of Janus Manager, a management software for rehabilitation centres in Iceland.

Join us to review and celebrate these accomplishments, and discuss how to carry them forward.

Description Weighing up the options: finding the right solution when lots of things matter - Talk at University of Stirling by Dr Sandy Brownlee 
Form Of Engagement Activity A talk or presentation
Part Of Official Scheme? No
Geographic Reach Regional
Primary Audience Postgraduate students
Results and Impact We can all think of a machine or a process that we'd like to be faster, cheaper, greener or otherwise better. Optimisation is the process of tuning something so that some aspect of it is made as big or small as possible. But what do we do when more than one thing is important? For example, we can make a car fast, comfortable or cheap, but probably not all together. There are many designs that strike different balances between these goals. Finding this trade-off between goals or "objectives" is known as multi-objective optimisation (MOO). This talk will introduce MOO and how it can be done automatically by computers intelligently searching through vast numbers of possibilities. I'll give examples based on my research in optimising buildings to be cheap to build, comfortable and energy-efficient, and show how MOO can be a huge help to designers.

Primary Audience Postgraduate students
Results and Impact Women form an under-represented cohort in evolutionary computation, whether the cohort is examined in industry, academics or both. The broad objective of this workshop is bring women attending GECCO together to share ways that will generate, encourage and support academic, professional and social opportunities for women in evolutionary computation. The workshop will foster, sustain and impart role models and offer the opportunity to interact with others "in the same boat". We encourage all faculty, professional and students interested in Evolutionary Computation who identify as female, who consider themselves underrepresented minorities with similar issues, or are male and supportive of the issues to attend.

Results and Impact Workshop given by Dr J Petke, Dr W Langdon and Dr D. R White
Summary:
Lately there has been enormous interest in the use of evolutionary and genetic search in optimising aspects of software engineering. For example, since 2002 there has been an SBSE track at GECCO. More recently there is a dedicated SSBSE conference. Indeed we now see regional conferences and workshops featuring or even dedicated to Search Based Software Engineering starting (in China, Brazil and now the USA). Including to appear, since 2000, there have been more than 70 papers in this area and interest is growing. Since 2009 there have been three human competitive awards (Gold, Silver and Bronze) presented at GECCO and two best papers, including the International Conference on Software Engineering and GECCO.
Whilst SBSE has traditionally been applied to software engineering problems there has been great interest in using it, particularly genetic programming, on software itself.
Genetic Improvement (GI) is the application of evolutionary and search-based optimisation methods to the improvement of existing software. The technique was first applied to optimise and find compromises between non-functional properties of software, such as execution time and power consumption. This work lead on to automated bug fixing in commercial software. More recently, it has been shown that GP can use human written software as a feed stock for GP and is able to evolve mutant software dedicated to solving particular problems. Another interesting area is grow and graft GP, where software is incubated outside its target human written code and subsequently grafted into it via GP.
