Re: Kibitz score reporting in server play

It looks like a 2 to 1 ratio in favor of scores reported from the program's point of view vs White's point of view. That's probably the reverse of what the opinion might have been a quarter century ago. Idea 1: express the score as a ratio of strength; this is commonly used in military calculations....

Re: Bounced from FICS

You might want to add the below formula for you engine, I have found that it gets rid of this type of abuse. rated & assesswin > 0 | unrated Done. Let's see if it helps. -------- Had one FICS game earlier today with opponent some 1000+ elo less than the program, but he somehow managed to do well --...

The 100 millisecond tax

I've just noticed something with FICS/timeseal on Linux/xboard: the program's per move search elapsed time is set to 100 ms (1/10 second) even for very small true search times. Symbolic's logs use a millisecond resolution timestamp on each output line and there are many times the program responds in...

Re: Bounced from FICS

If they wanted to clean up FICS, they would have done a better job with the same effort by booting every allegedly human account that had scored a victory over a program with twice the elo rating.

Re: Bounced from FICS

Symbolic's account has been reactivated and the program is playing as I write this. My idea is to use FICS as the initial public test area for Symbolic's Lisp cognitive search while the program's A/B searcher will be playing on ICC. I hope to have the Lisp searcher running on FICS early next month. ...

Bounced from FICS

I hadn't been using my FICS account recently but I tried doing so earlier today and found out that Symbolic had been bounced. Apparently they needed an updated application. Why, I do not know. Everything they wanted was already in the finger notes, the same situation as at ICC. If your program has a...

Re: WCSAC: nineteen possible cooks

I've decided to re-run WCSAC all the way from 1 to 65536 seconds per position on my 1.133 GHz P3 and these will take a couple of weeks. This frees up the 3 GHz P4 for ICC play; it runs at only 40% the throughput of the MacPro, so now is the time for everyone to siphon some easy rating points.

Re: WCSAC: nineteen possible cooks

I note that Fred Reinfeld, the author of the WCSAC analysis, was a bright guy and New York state champion for several years. But he had a few misses including a mate in one in WCSAC. (I corrected this in its first EPD release). Except for (possibly) some truly exceptional blockade positions, I trust...

Re: WCSAC: nineteen possible cooks

I re-ran the test at a fixed limit of 8,192 seconds (twice as long) per suspected cook and all nineteen remain suspected cooks.

More to come.

WCSAC: nineteen possible cooks

The following are nineteen possible cooks in WCSAC. Each analysis is the result of 8,192 seconds (2h 16m 32s) of work by a 3 GHz Pentium 4. I'm now rerunning these with a limit of 16,384 seconds.
