| Description | The key discoveries include new algorithms for capacitated arc routing problems in uncertain environments; a new formulation of robust optimisation over time to better capture and define characteristics of real world problems; a new dynamic scheduling algorithms for dynamic scheduling and its application in software project scheduling; a multi-population approach to dynamic travelling salesman problems; and a comprehensive review of railway rescheduling. |
| Exploitation Route | Our findings can be used by the academic communities for further studies both in terms of theories and new algorithms. They can also be investigated by non-academic sectors. We are actively organising workshops where we invite industrialists to participate and discuss our findings. |

| Description | This research was focused on computational studies of evolutionary dynamic optimisation algorithms. Its impact has been on the academic community. One of the highlights of this project was its study of dynamic multi-objective optimisation problems with a changing number of objectives. That was the first time a comprehensive experimental study was carried out and, as a result, a new evolutionary algorithm was designed. This work, published in IEEE Transactions on Evolutionary Computation in 2017, has attracted more than 100 citations according to Google Scholar. With knowledge gained during the investigation of dynamic evolutionary algorithms, we were able to developed new dynamic algorithms for software project scheduling and flexible job shop scheduling problems. Unlike most dynamic evolutionary optimisation at that time, we formulated a new and potentially more practical dynamic optimisation problem: robust optimisation over time. We explored potential links between dynamic optimisation and reinforcement learning. New algorithms for tackling large scale optimisation were proposed. |
