I found several related papers, which draws the following opinions.
- From [1], the current implementation of cmaes using resampling is somewhat reasonable.
- However, from [2], the performance of resampling becomes much worse when the optimum lies on near the boundary, compared to penalty-based methods. (But it is difficult to use penalty method for us, as ask-and-tell interface urges us to use the same points between the evaluation and the update.)
In conclusion, using resampling is not bad choice for now, but it may be a good idea to allow the use of the penalty method when the ask-and-tell interface is not used.
