Go up one level in this thread
Bob A couple of questions. Firstly, I've seen in a couple of posts you have give a measure of Move Order Quality as the percentage of cutoffs that are as a result of the first move played. Surely this is really a measure of Hash Table Strategy since it is the hash table move that is played first (Crafty's hashing strategy being sophisticated and including internal iterative deepening). Is it not the case that if you swapped Killer and History moves, the statistic would not change? Am I missing something? Secondly, when talking about Killers, is this the last (two) moves that created a cutoff at this level or do you store refutational killers ie a killer based upon the last move? Thanks Steve Maughan >I do it like this: > >1. transposition move >2. positive captures sorted by SEE score (best capture first) >3. killer 1 >4. killer 2 >5. history moves (4) >6. rest of moves, which just happens to do remaining captures first > since they were generated first. >
