Re: Sjeng 2.5 is a waste of money

I wonder if you tested movei progress 10 10 10 personality.

Jorge claims that progress 8 8 8 is better but my tests so far( that do not have enough games) suggest that it is not the case.

If Trace promoted to your premier league then maybe progress 10 10 10 can also promote to that league.

Re: New engine from Russia

My opinion is that the relative advantage of rybka beta is the evaluation. Rybka beta like fruit and toga does too many extensions(it seems to extend every check and every single reply by a full ply) so I cannot believe that the relative advantage of it relative to programs like shredder is the sear...

Re: CCRL update (4th May 2007)

Hello CCRL Team My questions is as follows: >all adjusted to the AMD64 X2 4600+ (2.4GHz). What does that mean? What are the REAL time controls you are throwing in to one pot for each tester? Have you ever made a rating list with this different time controls to see these lists are identical? Do you ...

Re: Symbolic: BWTC.0001 (12 nodes)

1. Bxf7+ was not included in the search because a forced mate was located first. The search concludes as soon as a forced result at the root is detected. The mate search does not attempt to find faster mates after a sure mate of any length is discovered. No claim is made that the mate attack/defend...

Re: New engine from Russia

<snipped> About a chess engine anything interesting I can not tell. Anything original there is not present. I dislike it. Even cloners who modify fruit or glaurung may have some original ideas in their changes. If there is nothing original in this engine we do not need it regardless of playing stren...

Re: Methods to stably evaluate nodes?

Especially at MP methods the node evaluations seems not to be determenisitic, because the result depends on the sequence of walking the tree. Thus I believe that some programmers do not even store such values into the transposition table, because one could never rely exactly on those figures. Are p...
