Hi bob, while uri can best explain Uri's intentions to you, I did read that thread. the programmers were talking about pruning. that is chosing which branches of candidate moves to follow and how deep to do that. this is a multi-ply issue of course. In contrast an evalation function looks at a chess position and applies a numerical function to it. In practice, say you loaded an epd in chessassistant. you may directly tell the gui which legal candidate moves to examine while ignoring others which are legal but you understand to be fruitless options. And then you might want to specify a ply-depth as well. I think this is what uri means by a searching function, only in the specifics of this thread he means it to be coded into the playing engine like the eval function. best regards-marc On March 11, 2004 at 17:45:55, Bob Durrett wrote: >On March 11, 2004 at 16:54:19, margolies,marc wrote: > >>hi bob, >>can you please make a citation of the post you were reading from. it might help >>me understand your need better. >>-marc >>On March 11, 2004 at 13:55:45, Bob Durrett wrote: >> >>> >>>A few days ago, someone was drawing a distinction between knowledge in >>>evaluation and knowledge in searching. >>> >>>I am intrigued and very interested in knowing more about "knowledge in >>>searching."
