PostPost subject: hashing, check extensions and depth    Posted: Sun May 27, 2007 8:32 pm Reply to topic Reply with quote

hi,

I use check extensions in my program ( pulsar ) and i also hash. I turn on extensions at a variable depth, like once its searched the first 2 ply. this means pottentailly that if a depth like depth 6 is hashed and it was hashed on ply 2, before check extensions, it may not be the same deepeness of search as something searched on ply 3 to 6 depth when check extensions were on for one additional level. Is this a problem? How would you correct it? I know how deep i searched when i hash in terms of where i came from but dont offhand know how deep i searched after the depth i hashed from. Some lines would get searched deeper than others if there was check extensions activated. I'm thinking it shouldnt matter to much but wanted to get others opinions.

thanks
Mike
