Hi Sean,

I don't want to evaluate useless rules. Also I don't want that these rules flow into my next generation. Because until now ECJ is only blind trying to find a good rule. It is not really an optimization of rules.

For this purpose I have to write a Breeder which can manipulate and mix a GPTree (that represents my rule). If  the result is worse than the originals it removes the created tree and tries again (until limit,  then using other GPTrees for mix)

I thought that is what a breeder does, or am I wrong? I appreciate any help.

Greetings

Bojan
