I'll tune my extensions a bit however. Just name the time and place. fixed depth=12 plies. To show you how stupid such a comment is... Might take me a few hours to search 12 plies however... >>On November 20, 2002 at 19:02:49, Gian-Carlo Pascutto wrote: >> >>>On November 20, 2002 at 18:54:30, Omid David Tabibi wrote: >>> >>>>>Could you please compare (Adptv + small quiesc) vs (Vrfd +small quiesc) ? >>> >>>When I have more time. >>> >>>If you want more data, I expect others will post results >>>from their programs as well.
