I uploaded the latest version of AI::Prolog. It's about 40% faster, incorporates math and has a workaround for the bug in older versions of Perl where undef looks like a number. Hopefully my test failures will go away.

Major performance improvement. Now runs about 40% faster.
Added towers of hanoi and a scheduler to the examples/.
