Re: [jgap-users] Reproduction by neighborhood

[Klaus M. <jg...@kl...>]

Simon,
 
good question. I think this is currently not implemented as JGAP core
functionality.
But of course you can do an implementation of your own:
 
1) NaturalSelectors such as BestChromosomesSelector or
WeightedRouletteSelector do select, which chromosomes will be passed from
the current to the next population 
2) Genetic Operators such as CrossoverOperator or MutationOperator change
single chromosomes, e.g. by crossing them over or by mutating them.
 
So it seems as you need at least a custom CrossingoverOperator.
 
If you have problems during implementation, please let me know.
 
Best

Subject: [jgap-users] Reproduction by neighborhood


Hi,
I'm trying to implement Cellular Genetic Algorithms using JGAP. This implies
that reproduction doesn't happen between any two chromosomes, but only
between two neighboring chromosomes. Is there something in JGAP that works
this way already? I'm looking but I haven't found anything. If not then I
suppose I need to implement my own, but I can't figure out if it's a natural
selector that I need to implement...

If you could point me to any way of introducing a way for reproduction
between chromosomes to be limited by geography.



Thanks a lot

Simon
