Computer Checkers

After reading Jonathan Schaeffer’s One Jump Ahead detailing his interesting march toward creating a world class caliber checkers player, I decided that it was a very interesting programming project. I had done some work on alpha-beta search way back in graduate school, but really hadn’t kept up with it, so I was basically relearning all the stuff that I knew back then, plus a bunch of new advancements and subtleties that I didn’t understand or appreciate.

So, my checkers program, Milhouse, was born.

I haven’t had the time to write this up, but I have made quite a bit of progress on this. It’s able to solve some pretty interesting problems. Try this one: white is to move and win. Milhouse sees the win in 0.3 seconds on my old desktop.

So I am out of practice a little but it took me over an hour! at work to solve this problem.
27-24,19-9,7×14,15-11,1×10,11-07,13×6,18×2,25×18,23×14,10×17,19-16,3×10,2-6,12×19,1×13
I am using being at work as an excuse for it taking so long but it was a tough problem. Got more?
