Re: Math question

I am working on a Polyglot book with a 32-bit WDL extension for a 1) better weight calculation, 2) better learn calculation and 3) maintain an opening repertoire. From the start position: I think it is interesting to try the multiple linear regression method. Our independent variables will be win, ...

Re: Bad Gyal 4a Released

Bad Gyal 4a The endgame data was problematic. This is a rerun without that data at 128x10. This should be the strongest net tactically, including T40, LD2. Tried it against UCI_Elo 1500 engines at TC 40/2min, it is too strong at this level. # PLAYER : RATING ERROR POINTS PLAYED (%) 1 Lc0 v0.21.2 Ba...

Re: UCI_Elo

Reduce strength by randomizing piece values of queen and rook. Before a search is made, queen is randomize between 400 to 700 cp, while rook is between 300 and 700 cp. This is on Deuterium v2019.2.37.54 ucielo 1500. Note basic weakening is at 200 nodes a move at this 1500 Elo level plus this materia...

Re: Position performance in a pgn database

Is there a command line tool that takes as input a epd or a FEN string and reports its performance in a pgn database? For performance, the white score percentage would suffice, but if it would calculates also the Elo performance would be even better. The module scoutfish.py can extract game headers...

Re: UCI_Elo

Reduce again Deuterium's nodes limit to 200, now it much closer to CT800. No other tricks added to reduce strenght so far, just the node reduction. Deuterium played on TC 3m+2s while I use TC 10m with 10s delay. # PLAYER : RATING ERROR POINTS PLAYED (%) 1 Amyan 1.72 ucielo 1500 : 2298.3 118.2 120.0 ...

Re: UCI_Elo

A sample game against Danasah using the chess GUI that I have been developing, featuring 2 TC's one with time delay. Danasah played at TC 5min+10s (Fischer), and I am on TC 5min-10s (10s delay). The pgn source has clk or clock showing the time remaining after a move. Press C8 on the board. [Event "H...

Re: UCI_Elo

According to uci protocol, UCI_Elo refers to Elo, since there is no other popular chess Elo than FIDE Elo, I believe this is FIDE Elo. Mark the author of Hiarcs is probably aware of this, his engine at 1500 uci elo is close.
