The American Checker Federation

2. It is only the prove that it is a drawish game. So what? This was assumed by almost all masters for centuries. In my mind Mr. Schaeffer wasted money to solve something that was not even in question. I accept a strong solution, but a weak solution is close to nothing. Like knowing that someone th...

I maintain that a stronger solution -- one where Chinook cannot turn a won position into a draw -- still would not require analyzing every single legal position that can arise in a game of checkers, because you still don't need to examine branches where both players have played imperfectly. So it'd ...

For instance, if you browse Chinook's game tree (http://chinook.cs.ualberta.ca/users/chinook/), you will notice that Chinook has not determined whether or not 11-15 22-17 is a draw or a black win. It does not matter for the purposes of a weak solution: Chinook knows enough - that 11-15 22-17 is not...

Re-read my last post. I showed why I think these two statements are equivalent.

Chinook team scientifically proved that GAYP is a drawn style. That's it. All other conversations about "strong-weak" solutions are only speculations. Chinook author never claimed they solved checkers, yellow media did ! :D Actually, yes, they did . "This paper announces that checker...

This is no an entirely accurate statement. Chinook didn't solve it at this level and Chinook still can miss a win - turn winning position into drawn. Then it isn't a proper weak solution. Since it was claimed to be a weak solution, it should never turn a winning position into a drawn position -- th...

I realize this thread is some months old, but there were some things said in this thread that I couldn't let pass without comment. First off, I don't think the following point has been made even once in the thread (correct me if I'm wrong): the difficulty of the game can be measured by the probabili...
