Description Mathematical tools for filtering, and the methods studied in this project are useful for monitoring and controlling many different types of systems. The mathematics is very central to many types of problem - from weather prediction to engineering. This research made a useful contribution to the overall challenges, and formed a foundation for future research of the PIs.
Exploitation Route High order methodology is mathematically challenging but very powerful. It can permit efficient anlysis of smaller datasets than might otherwise be the case.

Description Not directly, there is an useful paper which considers exemplar models and integrated the new theory with practical data analysis effectively. One hopes this will form a bridge to applications in due course. The methods did demonstrate orders of magnitude increase in quality of prediction, however they are intellectually challenging to implement and so the exemplar paper becomes important - but will probably require follow up to achieve a full transition into the wider community. However, indirectly it stimulated useful further research work on recombination and scenario management that potentially accelerates certain important cases of the simplex algorithm.
