报告内容简介：Evolutionary algorithms (or broadly speaking, meta-heuristics) represent a family of nature-inspired optimization techniques that have attracted much attention in recent years, due to their general applicability, robustness, and versatility. Many practitioners now realize EAs can offer significant advantages over exact methods, which often have strong assumptions. The adoption of EAs for solving difficult optimization problems is on the increase. However, there are still huge gaps when it comes to applying EAs to optimization problems considering more real-world characteristics. In the big data era, many practical problems are typically high dimensional, highly constrained, and combinatorial in nature. Furthermore, many optimization problems require the involvement of decision makers in the optimization process, rather than leave them out (i.e., human-in-the-loop). In this talk, I will describe some of my own experience in the past few years in dealing with applying evolutionary algorithms to several practical problems of this nature, including minimum cost network flow problems, resource scheduling mining problems, preference modelling for multi-criteria decision making. Since our primary goal is to design effective optimization techniques to solve problems of practical relevance, we deliberately avoided using test functions, typically constructed with too simplistic features far away from real-world scenarios. In this talk, I will focus on presenting the challenges we have encountered when tackling the above optimization problems.
