Yes, but....
It's correct because FindBestMoveInEval calls the smaller pruning neural
nets. These net's has only 5 hidden nodes. I don't think that's worth
vectorizing.
However... What if it was 8 hidden nodes? Or 12? I guess a vectorized 8
hidden node neural net would be even faster that a 5 hidden node net
unvectorized. Is feasible to retrain the pruning nets to have 8 hidden
nodes instead of 5?
Will it gain anything at all? Is it worth the effort?
Joseph? Any comments?
