Re: Challenge: predictive programs for WCC

Which program (as is) best predicts Magnus's moves in the WCC so far? Which program (as is) best predicts Anand's moves so far? Seems this could be a CCC project and we could work as a team to divide and conquer the solution space. Anybody interested? Maybe all the positions from the match from a p...

Re: TCEC Season 7 - Main Thread

This is the first time EVER in TCEC history that a Stage is played without books. Yes, that's right, in Stage 2 the engines are on their own from the very first move. Does anyone think this might not be fair in that some programs may be designed to play from a position AFTER enough opening moves, a...

Re: Senpai 1.0 (new engine)

2) Same reason as in 2005, I want to show that there is no need to rely exclusively on ideas from others in order to build a strong program. Originality does not imply mediocrity. I took a quick glance at your source. Very cool and original program. Nice to have some diversity in the gene pool. -Sam

Re: stalemate detection and pruning

Some time ago my program lost a game by playing into a stalemate, when it actually had a win. I found this hard to reproduce and never did fix it. But in thinking about it later, a possible cause has occurred to me. Stalemate detection depends on generating all moves and discovering none are legal....

Re: Multiple EVAL

I am toying with the idea to make my EVAL a standalone library which (starting) programmers can link to their engine. As such it can (for instance) serve as a second opinion EVAL during search or for other purposes, such as research. Furthermore I plan to pick one of the freely available sources ou...

Re: Hannibal 1.4 released

Thanks, great engine!! I was waiting for a MPV version, maybe in the next release? It is on the TODO list. We have been putting it off until the point at least some point were actually using the engine for analysis (rather than just for rating lists and such). It sounds like maybe its time to incre...

Re: 1 draw=1 win + 1 loss (always!)

The theoreticians would say that since empirical evidence indicates that two draws should count for more than one win plus one loss, the scoring system should reflect this. In what sense? In terms of producing a rating that predicts future results more accurately? If so, are these future results me...

Re: 1 draw=1 win + 1 loss (always!)

Thanks. One consequence of the notion that one win plus one loss equals less than two draws is that it gives theoretical validation to using number of wins as a tiebreak, I think. The current popular practice of scoring draws as 1 but wins as 3 might also be justified with this logic,although it se...
