Yeah, so I haven't been going to my AI class(shame on me) and I need to implement decision tree pruning. I really don't have any idea how to do this. I have the decision tree set up just fine and dandy and all that, someone have a link to a tutorial or want to explain this to me(with a possible algorithm)?

There are many many ways to implement pruning. Try looking up arc-consistency, node-consistency, forward checking, and maybe implement the most-constrained variable ordering heuristic. Those are the primary biggies for constructive search (and are pretty easy to implement).

[edit: sorry, disregard the above suggestions. I was thinking of constraint satisfaction tree's. Instead I offer this link:]

You seem to be on a similar topic as we are in my AI course. Are you using AI A Modern Approach? (AIMA) by Russel and Norvig as your book too?

Well, here's a decent link I thought:
