Sorry, I am hoping Tord will change the default settings for this or future version, that was the idea :wink: Would have been a much shorter post if I just said that, but there goes a lot of work in those matches, even if I do not have to play all the moves myself, as they used to do in the old days with dedicated computer tournaments. I believe there is a forum where they still do that and I hear chess-computer help is not even allowed anymore :)

Are their any settings for Glaurung 2.0.1.

So far it can't beat any other Glaurung or any other Engine.

So far its 0 for 30.

Are you saying it has scored 0 points in 30 matches?

Then my friend, something is wrong on your computer or your engine configuration.

How many threads are you using?
Did you remember to put exact number of threads on your computer?

If I remember it correctly , Glaurung has settings similar to Zappa, where you can adjust number of threads. If other engines are using 4 threads, and Glaurung only 1, of course it doesn't stand any chance.

Hi Werner,

This is what I have been testing

Selectivity: 5 (1 step down from default 6)
Single Reply Extension (PV): 2 (1 up from default 1, 1 is a half ply I believe)
Single Reply Extension (non PV): 2 (1 up from default 1)

Regards, Eelco

3rd result with Mjolnir 001b settings compared with Default

Post by Eelco de Groot »

The third match was a match against Shredder 9 playing with its own book. Again a match of 22 with Mjolnir settings and a match of twenty games with default settings.

Sometimes you see that settings perform relatively better at a certain timecontrol. A possible reason for this could be that in that timecontrol it often manages to complete plydepth x where the opponent has trouble completing plydepth y. This match was played with 50% longer timecontrol 12 minutes + 3 seconds, to counter this effect.

_____________________________________________________________
Comparing the two matches, Glaurung 2.0.1 won both of them! Congrats to Tord!

Glaurung 2.0.1 Mjolnir 11½/22 = 52%

Glaurung 2.0.1 default 11/20 = 55%

Difference -3% ≈ -21 elopoints in TPR this time. Not a big loss for Mjolnir. Also to be taken into account is that Shredder and Glaurung were now using a different book. This means that in the two game matches openings could not be repeated and there is more variability in the results.
