Howdy. I just had a tutorial posted on AI Depot : Decision Trees and Evolutionary Programming. If anyone is interested in reading through it, I would truly appreciate feedback on the concept and the methods. The grammar most likely is terrible, but please hold those comments or at least be gentle. 8^) -Kirk [edited by - KirkD on December 9, 2002 9:37:18 AM]

Hi,

I read through your article and overall think it was very good.

My only complaint being that you do not go in to enough detail of the random mutations.
I understand the principle of this matter but would it be for example swapping the child nodes around e.g. in figure 4 A mutation might be if enemies are nearby, yes=eat, no=hide, and where this would obviously reduce the fitness factor some mutations might be good.

Thanks, Meto

Good point!

The mutations I used were applied only to nodes (not leaves) and consisted of moving the decision point one point to the numerical left or right, changing the decision point to a random value for the chosen feature, picking a new feature at random, or completely regrowing the subtree rooted at that node.
