DOLPHIN : Parallel Cooperative Multi-criteria Optimization (project-team)
Project-Team Presentation
Joint project-team with LIFL (CNRS and Lille University - USTL), located in Lille.
Many industrial domains are concerned by large and complex optimization problems, involving important financial costs and in which decisions must be taken in an optimal way. The development of advanced hybrid optimization methods from combinatorial optimization in operations research, decision in artificial intelligence and parallel and distributed computing, is an important issue in solving in a reasonable search time this class of problems, which are more and more complex.
The goal of the DOLPHIN project-team is the modeling and parallel resolution of large (multi-objective) combinatorial optimization problems. Efficient parallel cooperative optimization methods are developed from the analysis of the structure of the solved problem. The target optimization problems are generic problems (flow-shop scheduling, vehicle routing, etc.) and industrial problems from telecommunications and genomics.
Research themes
- Analysis of the structure of a combinatorial optimization problem, where many indicators are used to analyze the landscape of the problem. This allows the efficient design of search operators, objective finctions, and hybrid methods for solving mono-objective and multi-objective problems.
- Cooperation of optimization methods (metaheuristics and/or exact methods), to combine complementary optimization strategies.
- Parallel optimization methods, to speedup the search, to solve large problems, and to improve the robustness and the quality of solutions.
