Re: Thematic move heuristic

I think he means isolating specific patterns or pattern fields. For example, I'd guess more than 75% of my games have at least one of the player with three pawns in front of a castled king. An engine could detect this pattern and somehow reduce or extend specific moves. But seeing as how computers a...

Re: Thinker is blowing my mind

The developmental version of Thinker plays on FICS under the Thinker(C) handle. Considering the hardware it runs on, the engine appears to be in line with or better than the Rybka's. I wouldn't be surprised to see Thinker in the top three at the end of the WBEC, but I agree its too early to call.

Re: Parameter tuning

Does anyone know of a competitive engine whose parameters are loaded from an ini file? I'm a real fan of these types of tuning algorithms and I'd like to be able to just adjust an ini file instead of recompiling a program in order to tune it.

Re: lazy eval discussion

I reread your post. I had originally taken it to mean you had just added two break points to the eval function to exit early and you were testing them to find if there was any ELO. Now I see you had those two points in there all along and were trying to put an ELO value to them.

Re: lazy eval discussion

Could this be caused by a bad range for the window?

Re: Parameter tuning

I find it somewhat ironic that most engine developers are quick to scorn tuning engine parameters to one position or based on one game (because you may fix one position and break 10 positions), yet they will do 100,000 games tuning their engine solely against itself. I'll admit that x' vs. x matches...

Re: Playing better moves in drawish positions (anti-0.00)

Maybe I'm misunderstanding you Mr Muller, are you saying to score a draw positively? a positive score for a draw is counterintuitive for me. I'd think in general you would want an engine to avoid a draw when winning or even and to seek a draw when losing. Wouldn't this be achieved by a slightly nega...

Stockfish's contempt value

Can someone explain how Stockfish determines if it should take a 3-fold rep draw or not? I run Stockfish on FICS as continuously as possible. Something that really gets my goat is the ability of low rated humans to obtain an early 3-fold rep draw all too often. I don't know how frequently it occurs ...

Re: Feedback from XBoard users sought

I only use Xboard in -ics and -zippy mode and there are a couple of things I'd like to comment on: 1. Whenever you close a dialog, it shows something in the terminal "xWidget exited unexpectedly" if I recall (or something very similar). It doesn't affect anything really, because the settings take, b...

Critter 0.90 for Linux?

I can't for the life of me find a recent release of Critter for linux. Does anyone know if one exists? 0.90 would be best, but 0.80 would still be good.
