Xin Yao's Research Interests: Constraint Handling Techniques and
Constraints appear in many practical problems. I am interested in various
constraint handling techniques that are not specific to any one algorithm. At
present, I am trying to get a deeper understanding of what penalty methods
do in transforming a fitness landscape and how such transformation influences
evolutionary search. One of the aims of the research is to explain why penalty
methods work well in some cases but not others.
