Re: WinBoard engines incapable of playing incremental clock

I am not sure I understand the question. I'm going to comment on an example, the TSCP engine. TSCP has a very simple time control management. When TSCP plays a time control such as x moves in y minutes and the time control is repeated, TSCP does not know how many moves are left for time control, so ...

Re: Trying to use ProDeo book in my program

I have used the book of rebel in DanaSah. Like you, I started using the dll and finally integrated the code. Like you, I had some problem compiling, so I made some small change until I got it. At first I used the microsoft compiler and later gcc. With some tool like winmerge you could see the change...

Code: Select all

struct Entry{
    Move m; //int
    Hash h; // int64
    ScoreType score, eval; //short int
    Bound b; // char
    DepthType d; // signed char
    short int generation;
};
This is not 20 bytes?

4 + 8 + 2 + 2 + 1 + 1 + 2 = 20

Re: UCI_Elo

Run a new RR with uci elo 1500 engines at TC 60s+100ms. New engines are Rybka, Rodent, Danasah with engine opponent setting, new version of Stockfish and my new engine version. Thanks for testing DanaSah. I have a new version (beta) with limited strength, I think I didn't publish it here. If you do...

Re: UCI_Elo

Any advice to tune engine parameters to correspond to the right UCI_Elo value ? In Cheese I have 2 parameters, one to make very small pauses every N nodes, and another one to add randomness to the evaluation under 2000 ELO. If we cannot find a reference engine and corresponding UCI_Elo value we mig...

Re: New Tool for Tuning with Skopt

Once I have played a series of games and I have the file data.log, if I run the test again and use the file, in each run I have different results and the results seem quite random. ... Using [8.0, 90.0, 5.0, 114.0] => 0.5 from log-file Using [1.0, 144.0, 1.0, 121.0] => 0.0 from log-file Using [9.0, ...

Re: Dedicated Chess Machine Elo vs Human Elo, a least squares analysis

There is a thread in which Larry Kaufman indicates that he estimated that it could be passed from Elo CCRL to Elo FIDE with: Elo FIDE = 0.75 x Elo CCRL + constant. Kai seems to have done a study and gave the formula: Elo FIDE = 0.7 x Elo CCRL + 840 I guess the Kai formula is for CCRL 40/40 and I don...

Re: Dedicated Chess Machine Elo vs Human Elo, a least squares analysis

I suggest that you face engines of approximately 1600 Elo CCRL points and see if you can win them by complying with time control. If the engine plays in 15 seconds and you respond in 2 minutes, you are using 8 times more time, this could mean by your rule of 75 points; 75 + 75 + 75 = 225 points mor...

Re: Dedicated Chess Machine Elo vs Human Elo, a least squares analysis

Uri, The article tries to establish a relationship between the Aktiv list of dedicated chess machines and the FIDE list. The fact that the Elo FIDE starts at 1000 points or the Elo USCF at 100 is not something critical for what the article tries to explain. The article is not recent, maybe 4 years o...
