contempt 20 vs 0 at VLTC : no loss of performance

Hi noname,
basically part of SF team realized that adding adaptative contempt as it is now implemented does not alter the performance in self play, while reducing the draw rate against weaker engines (so more wins).
Ivan Ivec opened a pull request to put a contempt value of 7 as default for SF. But later tests tend to prove that contempt values as high as 20 do not alter self play, while adding like 15-20 elo against weaker (like SF7) engines.

Hi Mrert, any contempt work is good ☺
btw, any idea what 25812 means ❓

Looks like the new contempt algorithm yields quite interesting results.

hi @sfs,
go to https://github.com/lantonov/asmFish. Then download the Download.zip and open it. Double-click on the batch file "make". Cmd pops up and then you enter the number for your operating system, for example 2 for windows. Then double-click on the "fasmg .exe". Done the asmfish.exe is created.
I do not know how to switch to the old time management. There is a TimeMng.asm. Maybe you can swap those with an old (otm) version. For stockfish you just have to replace the 3 files timeman.cpp, timeman.h and ucioption.cpp. Maybe @KingLearbe or @noname can help you.

Hi, the old time management is back. Does anyone know how to create an exe file from the current ASM Master 170110? There is only the sorce. Is it possible to include the oldtimemanagement ? I could not create an exe with Mingw. Which compiler is needed for the .asm files? Thanks in advance for your help.

The A.R.B Chess System...

Official Site :) https://www.youtube.com/user/COMPUTERSTOPBUILD/videos

https://chessprogramming.wikispaces.com/The+A.R.B+Chess+System

An opening system developed by Anthony.R.Brown more than 35 years ago (1983) (as of 2018) as a response to the growing strength of Chess engines
The apparently passive system gives the programs a FALSE! initial space advantage by allowing them to push center pawns Etc.

(In 1983, the first chess microcomputer beat a master in tournament play. BELLE became the first chess computer to attain a master's rating when, in October, 1983, its USCF rating was 2203)

The A.R.B Chess System is the First & Only Chess System in the History of Chess to play (6)
Pawns first in the Opening before any Main Pieces are played :)
Whether playing White or Black...

The Six Pawns for White or Black (Reversed) are Moved forward by one rank only,
Except if there is a Need to Block a Check or Stop a Piece being Captured Etc.

The Move Order is One of the Most important things concerning how the First Six Pawns are Played!

Below Playing for White is how the System plays the first Six Pawn Moves in Move Order Preference...

1. e3 (Most Moves!) 2. d3 (Most Moves!) 3. h3 (Most Moves!) 4. a3 (Most Moves!)
5. g3 (Most Moves!) 6. (Most Moves!) b3

And Below Playing for Black is how the System plays the first Six Pawn Moves in Move Order Preference...

1. (Most Moves!) e6 2. (Most Moves!) d6 3. (Most Moves!) h6 4. (Most Moves!) a6
5. (Most Moves!) g6 6. (Most Moves!) b6

Other strategies are characterized by closing the center, no or delayed castling , and provoking other early pawn advances by the programs,
yielding in long term weaknesses.

He's like a 2 year old screaming for attention in a grocery store.
Is there any way to adjust setting to ignore it?

@sam
Hi, if the evaluation function get more complex (new evaluation term for bishop or pawn for example), the speed will get slower (less N/s).
So, it is a a trade between speed and accuracy.
All in all, the latest stockfish version is the strongest, with few exceptions (sometimes there are regressions, which are corrected later).

hi people, can someone tell me what the bench test (cmd: uci enter bench) has for a meaning for the strength of a Stockfish.exe? For example, I have the following values for the Stockfish_18010422.exe: TotalTime = 2719ms, Nodessecond: 4919682, and Nodes / second = 1809371.
Stockfish_17120318.exe has the following values: TotalTime = 2752ms, Nodessecond: 5051254, and Nodes / second = 1835484. Is here the Stockfish_17120318 in the example stronger than the Stockfish_18010422.exe, because more Nodes / second? Thank you

Hi KingLearbe, long time ☺

Yes you're right, major code changes will render that method useless.

Fritz (chessbase guis) unfortunately still don't follow the UCI protocol fully, so sometimes there are new issues when src changes are made 😯
Engine authors usually have to concede to chessbase and publish an updated version like Houdini 1.5 to 1.5a, and I think Critter 1.6 to 1.6a.
I don't think SF authors do that though 😐

The good thing with SF is we can look through the code ourselves and try to find workarounds for poor src changes that don't work properly ☺

@noname Hi I see you are still on call helping people here :) I have been watching in from time to time. As you see I have used some of the threads you have posted on OTM and NTM. For now it is solved by copying in the OTM :) Unfortunately this will hold only as long as there are no changes in how the TM files are called upon. As soon as there is a call from the engine that applies only to code in the NTM this will fail.. However we will cross that bridge when we come to it which is hopefully never...;)

I do not know whether I am the only one but I encountered some problems with the changes made in by Author: Joost VandeVondele
Date: Mon Jan 1 13:17:51 2018 +0100
Timestamp: 1514809071

The clearing of the memory for the transposition tables seems to cause some strange hiccups in the fritz gui while playing at Playchess. Multiple windows remain open, games remain open and frozen. I do think that the clearing of the memory before each game or resizing causes problems for servers like playchess as they are not expecting this behavior.

It is in it self a very good change and really does speeds up the first move.
Now we only have to convince Playchess to adapt to this behavior.. ;)

Well greetings for now I will keep looking in from time to time. Always interesting to read...
