Workshop on Problem Understanding and Real-World Optimisation
Saturday 6th July 2013
DOWNLOAD WORKSHOP PROGRAMME
This workshop sees the joining of two related workshops to reﬂect the link between stronger methods in problem understanding and the signiﬁcant importance of scientiﬁc approaches to tackling real-world optimisation problems. This workshop will address the wider topic of scientiﬁc methods for analysing and solving difficult and real problems currently faced by optimisation researchers.
The workshop will continue the themes of last year’s GECCO-UP workshop and aims to provide a forum for the discussion and exploration of methods for the analysis, creation and synthesis of optimisation problems through both theoretical and experimental methods. A crucial aspect of this research is developing problems that reflect the complexity and idiosyncrasies of real-world optimisation problems. Therefore, the workshop will open with a session focused on real-world optimisation problems, in which speakers from both industry and academia discuss their experiences of what makes real-world problems difficult. The workshop as a whole provides an opportunity for discussion and interactions that might move towards bridging the gap between those problems addressed by scientific research and the types of problem addressed by commercial optimisation software vendors.
Furthermore, the continued the ethos of open debate of the previous workshops will be upheld in a discussion session held at the end of the workshop which will give an opportunity for participants to discuss and present recently published research and position papers.

Prof Emma Hart Prof Emma Hart is an experienced researcher in the area of optmisation and hyper-heuristics, being one of the original authors of the term’hyper-heuristics’ in the early 2000s. She has published widely on the use of evolutionary algorithms applied to scheduling and timetabling problems, as well as in hyper-heuristics applied to a variety of domains. She is currently the holder of a large national research grant, investigating the use of hyper-heuristics that continuously learn and improve over time, which has collaborators from the logistics and forestry industry.
Kevin Sim is a researcher who works in the field of hyper-heuristics and problem-classification algorithms, and works with Prof. Hart on a large national grant on hyper-heuristics. He is also co-chair of a workshop at Evo-Star 2013 called EvoIndustry.
Kent McClymont is an Associate Research Fellow in Computer Science at the University of Exeter. His research is focused on the study of optimisation problem analysis and multi-objective hyper-heuristic methods for solving hard real-world optimisation problems. Kent has a specific interest in heterogeneous encodings for which he has published a novel test problem suite and is continuing work in this area. He is a member of AISB committee and was is a member of the AISB 2013 Convention’s organising committee and has chaired sessions at previous GECCO and IEEE CEC.
Ed Keedwell is a Lecturer in Computer Science at the University of Exeter. His research is focused on Nature-Inspired Computation techniques and their application to real-world optimisation problems in engineering and bioinformatics. He has published almost 50 papers in this field and currently leads a group of 8-10 postgraduate students and postdoctoral researchers. Dr Keedwell is co-chair for the AISB2013 Convention and is organizer of a symposium for AISB 2013 and chaired sessions at previous AISB conventions and IEEE CEC 2010.
