My software needs to choose "good" start point for GA. The GA is choosing points which define membership functions for Fuzzy logic controler. I need to inclued constrains which will make sure that these points are not the same (I want triangle MFs).
1. How can I include constraints - GA chooses initial population and these constraints need to be included

abs(x1-x2)<0.1 and x1<x2

(where x1,x2,..x30. are points that define MFs).

If I try to define constrains as function or as linear constraints but then they are not applied on intial population.

Any ideas?

Many thanks

Supply an initial population. See "Initial population" in
