cutechess-cli 0.7.2

[Ferdy]

Hello,

just some easy little questions about cutechess parameters.

1. What is the trust parameter used for ?

Code: Select all

trust
Trust result claims from the engine without validation. By default all claims are validated.

Probably intended for xboard/winboard engines.

2. Does the st parameter accept fractions of seconds, like 0.25 ?

No.

3. What is the use for the inf parameter ?

Code: Select all

tc=[tcformat | inf]

This is probably a form of infinite time. Say you may want to do a fixed depth search game for example

Code: Select all

depth = 12 tc=inf

The engine in this case cannot be forfeited due to time, because of inf. If for example

Code: Select all

depth = 12 st = 1

The engine can be forfeited due to time if it exceeds 1 sec without sending its bestmove.

No.

I have to correct this, the answer is yes. Values less than 1 sec is correctly converted to ms.

Code: Select all

// Search time per move
	else if (name == "st")
	{
			bool ok = false;
			int moveTime = val.toDouble(&ok) * 1000.0;
			if (!ok || moveTime <= 0)
			{
				qWarning() << "Invalid search time:" << val;
				return false;
			}
			data.tc.setTimePerMove(moveTime);
	}

2. Does the st parameter accept fractions of seconds, like 0.25 ?

Yes.

If so, should timemargin be used with st parameter ?

The timemargin can be used with st.

Hi, Ferdi,

thanks for your explanations.

@Ilari

So, finally here is my wish list for a future version of cutechess-cli:

* knockout tournament mode

Now all I need is time

After some tests with version 0.7.3, I encountered this "has no side" warning. This is the first time I encountered it and actually stopped the whole match before it is finished.

Here is a compile for windows with following changes. This is still unreleased but code changes are already available. I think these changes are significant, so just for those interested.
1. Fix FEN tag in the header of a game. Now the FEN has hmvc and fmvn.
Sample.

[Event "?"]
[Site "?"]
[Date "2015.09.25"]
[Round "1"]
[White "D2015.1.262"]
[Black "Gaviota v1.0 64bit"]
[Result "1-0"]
[FEN "2rq1rk1/pb1n2pp/1pp1p3/3pPp2/2PP1PPb/P3B2P/1PQ3B1/R2R1NK1 b - - 0 1"]
[PlyCount "109"]
[SetUp "1"]
[Termination "adjudication"]
[TimeControl "60+0.1"]

1... fxg4 {-0.33/11 1.3s} 2. hxg4 {-0.02/13 2.1s} Qe7 {-0.36/11 1.7s}
3. Qe2 {-0.18/13 5.4s} Ba6 {-0.35/10 1.2s} 4. g5 {+1.21/13 0.85s}
Bxg5 {-1.39/13 1.2s} 5. fxg5 {+1.06/15 1.8s} Bxc4 {-1.45/14 1.2s}

2. (windows) Make sure engines are killed along with CuteChess.
Now even with Control+break (was only control+C) keys to interrupt the running tour, engines are exited/quited/killed along with cutechess.

Be aware the version number is still 0.7.2 when you send the command cutechess-cli -version.

I have not encountered problems with this update version so far. It is encourage to report problems, warning messages and others if ever you encounter one. This would help the developers to further improve the tool.

and download 0.7.2.

Is it possible for someone to make this compatible with CuGen?

Will it also completely terminate processes still hogging memory? I'm using 0.7.1 and the only tournament that really works is "match". As soon as you have 3 or more engines, both gauntlet and round-robin will ignore the "restart" parameter; no matter what option you specify, engines will be restarted, and the "terminated" processes will still be using memory:

- a few dozens will still be requiring the full 100% they peaked at (Working set as reported by Resource Monitor)
- the rest will occupy a modicum of 20K, which amounts to quite a bit when they number in the thousands (RAMMap)

In the end, you run out of memory and the tournament is exited abruptly.
