讲座摘要:Multiobjective Evolutionary Computation has been a major research topic in the field of evolutionary computation for many years. It has been generally accepted that combination of evolutionary algorithms and traditional optimization methods should be a next generation multiobjective optimization solver. Decomposition methods have been well used and studied in traditional multiobjective optimization. It is well known that the Pareto optimal solution set of a continuous multiobjective problem often exhibits some regularity. In this talk, I will describe two multiobjective evolutionary algorithms: MOEA/D and RM-MEDA. Both of them borrow ideas from traditional optimization. MOEA/D decomposes a multiobjective problem into a number of subtasks, and then solves them in a collaborative manner.  MOEA/D provides a very natural bridge between multiobjective evolutionary algorithms and traditional decomposition methods. It has been a commonly used evolutionary algorithmic framework in recent years.  RM-MEDA makes use of the regularity property to model the distribution of Pareto optimal solutions in the search space, and then generates new solutions from the model thus built.  Machine learning techniques can be readily used in RM-MEDA. I will explain the basic ideas behind these two algorithms and some recent developments.   I will also outline some possible research issues in multiobjective evolutionary computation.
