Are you refering to Prof. Paul Utgoff of the University of Massachusetts?
I know they have an AI course in which the students are required to write
their own Freecell solvers:

33-deals per second at 81 MHz is definitely impressive. When are you
planning to release some version of your code?

If:
1. A is A
2. A is not not-A
does it imply that
1. B is B
2. B is not not-B
