• Best paper award at GECCO 2015 (ECOM track, Madrid, Spain, 2015) for the paper “Global vs local search on multi-objective NK-landscapes: contrasting the impact of problem features” , by F. Daolio, A. Liefooghe, S. Verel, H. Aguirre, K. Tanaka. This work is part of our collaboration with Shinshu University in Japan (Associate team s3-bbo and JSPS-MEXT project) on fitness landscape analysis and search performance. In this paper, we consider two prototypical multi-objective optimization algorithms and relate their performance on combinatorial optimization problems with tunable ruggedness, objective space dimension, and objective correlation. Our study departs from simple performance comparison by systematically analyzing the correlation between runtime and problem features, contrasting their association with search performance within and across problem classes. A mixed-model approach allows us to further generalize from the experimental design, supporting a sound assessment of the joint impact of problem features on the search performance.

• Best paper award of “11^th Intl. Conf. on Parallel Processing and Applied Mathematics" (PPAM'2015, Krakow, September 6-9). assigned to Jan Gmys, Mohand Mezmaz, Nouredine Melab and Daniel Tuyttens for their article entitled "IVM-based Work Stealing for Parallel Branch-and-Bound on GPU" . This work falls within the framework of the Ph.D thesis of Jan Gmys from University of Mons in cotutelle with Université Lille 1. The contribution consists in revisiting on GPU the parallel design and implementation (based on the Work Stealing paradigm) of the Branch-and-Bound algorithm applied to permutation problems. The raised challenge, which is the originality of the contribution, is to efficiently perform highly irregular exploration process entirely on the GPU having a SIMD architecture.

• Thesis Prize: 26th Nov 2015: Julie Jacques (Phd 2011) won the "Force Awards Nord de France" trophee in the category "thesis with an industrial". Her thesis work, in collaboration with the Dolphin team and the Alicante company, aimed at providing new datamining approaches in order to optimize inclusion in clinical trials.
