TCEC groupe stage

[mar]

How did FireFly and Myrddin get selected for TCEC ?

They are about 1000 elo behind many good engines that were not selected. Why not a random mover while we're at it ?

And do not have SMP. I thought one of the pre-requisite of TCEC was SMP.

Of course they're no random movers and they both have (working) SMP.

In a previous session Komodo played with a core only,
Hakkapeliitta almost certainly will soon be SMP.

I think that Lucas wants to say that there are a wide variery of original engines (I mean, neither clones nor derivatives) with much more Elo than FireFly and Myrddin. Just taking a quick look to CCRL 40/40 rating list, I see Senpai (probably not included because Fruit is already in group 1B), Spike, Spark, Zappa, EXchess, Crafty... and none of them will play in TCEC 9. We do not know about stability issues, like Junior in the past. Is that the main reason? One thing is sure: the organizers decide which engines play and which not, and might be additional, subjective criteria other than raw Elo (style, crazy attacks in the a priori one-sided games, etc.). Just my opinion, in line with Guenther's.

Hi Jesus,

I think that Lucas wants to say that there are a wide variery of original engines (I mean, neither clones nor derivatives) with much more Elo than FireFly and Myrddin.

That can be done while also showing respect to the authors.
How much elo is necessary to show respect?

Well for example I dediced not to participate; also you can't force anyone to participate, you have to ask the authors why.

I'd personally like to see Dirty and also Crafty to see how Bob's improved SMP works on 20 cores, but it would be a handful of games anyway.

Regarding myself, it is well known that I respect a lot authors of every engine, regardless of their strength. I have stated it many times here. And when I say 'regardless of their strength' I include random movers. People that can manage to create an engine that plays legal chess is incredible for me, it is a milestone. I am not a programmer and I realize the amount of effort and the fact that I will not be a chess engine author ever, lacking both time and skills.

It is a thing that I forgot: the refusal of the authors. Other possibility is that currently developped engines are chosen: it could be applied to Spark and Spike... but Critter will play in group 1B, and I think that those three engines have the same discontinued/inactive status. Speculations, speculations everywhere!

I agree, it would be nice. If we know the hardware of TCEC 9, we could do some extrapolations of kN/s, time to depth or whatever and compare them with the true results of this handful of games. Maybe next time.
