[plt-scheme] AI Algorithms in PLT-Scheme

There is the inference collection for backward and forward chaining
inference that is on PLaneT (in fact, I just updated it for PLT Scheme 4.0
today). And, I have some graph search algorithms for state-space problem
solvers (with examples) and a blocks world program, with how and why
explanations based on walking the solution tree, that aren't on PLaneT, but
that are written in PLT Scheme. I'd be happy to make those available to you.
