It is a ridiculous statement. Only down-side is that I doubt I will live long enough for the idiocy of that statement to be prov...

Re: Fruit and History Reductions

I interpreted Bob's 'history stuff' as anything that depends on the history tables (e.g. reductions as well as move ordering). that was my intent.

The moves after that are regarded as "late" in LMR (Late Move Reduction) History Treshold: You want to reduce "Late moves" (as above) but first you check that moves his...

Re: Fruit and History Reductions

Could you please tell me about those methods? It has been some time I don't read the latest crafty's source. Are those implemented in the latest version of crafty? best regards, alvaro Source will be available soon. But simply we look at each individual move to decide whether to reduce it or not. A...

Some progammers think speed is everything, so they will never do it right. BTW, I posted a similar ga...
