For example you can use
tc=inf depth=1
A game is really fast with this.

Then why this result:

Code: Select all

Score of A-Random 5+0.05'' vs A-Random depth=1: 0 - 54 - 0  [0.000] 54
ELO difference: -inf +/- nan
54 Wins for depth=1.
It seems in your conditions Andscacs is playing depth=1 games rather than random moves. While 5''+0.05'' really plays randomly.

I see. It needs at least depth 2 games to enter the main loop and play random moves.

Yesterday I implemented what I see as a natural improvement to a random mover. It is an engine that behaves like a random mover with one exception. Whenever there is a mate in 1 it will mate. Here the results (W-L-D) from 100000 games random mover + mate vs random mover played with cutechess last night.

Code: Select all

Score of Arminius RND+MATE vs Arminius RND: 53276 - 5507 - 41217 [0.739]
ELO difference: 180.66 +/- 1.67

100000 of 100000 games finished.

Daniel, is there something in Andscacs which prevents it playing for more than 500 and a few moves? I get "disconnect" in Cutechess-Cli for this kind of games between A-worst engines (at fixed depth, so there is no time forfeit issue, but it happens in any condition):

Or it is Cutechess not playing above 500 something moves? This is occurring often, the histogram of length of played games between two A-worst engines looks like this:

All those little above 500 moves are "disconnects" and arbitrarily adjudicated as losses (and as wins for the other side). Otherwise most games are drawn. No games are longer than 510 or so moves, they become all "disconnect" and losses/wins.

Thanks!

For example you can use
tc=inf depth=1
A game is really fast with this.
Then why this result:

Code: Select all

Score of A-Random 5+0.05'' vs A-Random depth=1: 0 - 54 - 0  [0.000] 54
ELO difference: -inf +/- nan
54 Wins for depth=1.
It seems in your conditions Andscacs is playing depth=1 games rather than random moves. While 5''+0.05'' really plays randomly.
I see. It needs at least depth 2 games to enter the main loop and play random moves.
Daniel, is there something in Andscacs which prevents it playing for more than 500 and a few moves? I get "disconnect" in Cutechess-Cli for this kind of games between A-worst engines (at fixed depth, so there is no time forfeit issue, but it happens in any condition):

Yeah, I had wondered why the draw rate was so low, because I had expected much more draws, because it is not easy to force a mate for a true random mover against a 'worst' player.
(does the worst player also look for forced help mates? BTW if the worst player would know he plays against a true random mover, he could avoid
too much random possibilities in escape moves for forcing more chances to be mated)

I suppose there will be quite some stalemates and we will trigger a problem with game length :)

Default Winboard compile has a max moves 500 build in too.
Scid vs. PC out of the box handles even more I noticed.
(other GUIs might already choke on move 300, e.g. CB)

HGM could you compile one with a max of 1500? I would like to do
some tests for this with andscacs loser/random players.

Daniel, the loser should also avoid _any_ repetition. It does not help losing the game and more important game lengths blow up by a huge margin.

I don't think you can do that. There are plenty positions where repeating is the only way to save the draw. E.g. in KPK:
[d]8/8/4k3/8/8/4K3/4P3/8 b
Say the above position results from a capture (Kxe3). Black's only chance to draw is take and keep opposition

1... Ke5! 2. Kf3 Kf5! 3. Ke3

This is not yet a repeat, because the previous time the white King was on e3 the black one was on e6, not on f5. But if black is now not allowed to play Ke5, because that will be a repetition, he has to play something else, after which white plays Ke4 and wins.
