Thread Subject: genetic algorithm niching methods?

Are there any niching methods available in Matlab for use with the genetic algorithm optimiser?

If you are using the multi-objective GA function (GAMULTIOBJ) it has a crowding model implementation (see the option DistanceMeasureFcn) that can be useful. You can use this function to optimize one or more objectives (no nonlinear constraint support yet).

In general, I like crowding model over niching because you don't have to know 'niche count'.


Hope that helps!
