So now I'm going to hand it over to Mike who's going to talk about the part of the code that we parallelized. And the computer makes its couple of moves.

If it wasn't for the lop-sided dice rolls it would be a great game. Dice rolls are not randomized. Oh, so that's time scale of the absolute? And one of the important features was it adjusted the weights as the game went on, because certain features became less important as the game progressed and other features became more important.

Some important rules are that you can not land on a point on which your opponent has two or more pieces. And he sort of released this as a benchmark evaluator so that other people in the development community could have something to compare their evaluators against.

And looking at what the program has to do in running the game, that's the next thing we want to tackle as far as paralyzing goes. Eddie Scholtz and Mike Fitzgerald. No enrollment or registration.
