TCEC groupe stage

[JJJ]

It seems that Stockfish will play the "easy" group.

On facebook, they says to stay tuned because of particular case of Houdini and Rybka, any idea about what they mean ?

Houdini 5 is expected to replace Houdini 4 at some stage.

Fritz 15 could replace Rybka 4.1 at some stage.

Ah, but nothing new with Houdini.
Ok for Rybka, nice !

Hello Jean:

It seems that Stockfish will play the "easy" group.

I do not think so. I would have done the pairings the same way: given the full rating list of participants, group 1A has all the odd ranking places (1st, 3rd, 5th, ..., 29th and 31st) and group 1B has all the even ranking places (2nd, 4th, 6th, ..., 30th and 32th).

Regarding ratings and averages, everyone must expect a higher rating average in group 1A due to the chosen pairing method. But how much? If I am not wrong:

Code: Select all

<Rating &#40;1A&#41;> = 2978.75   Elo.
<Rating &#40;1B&#41;> = 2940.0625 Elo.

Without including the leaders of both groups (Komodo and Stockfish):

Code: Select all

<Rating &#40;1A&#41; | without Komodo>    ~ 2953.47 Elo.
<Rating &#40;1B&#41; | without Stockfish> = 2913.4  Elo.

Furthermore, if you look at the a priori most difficult engines for the group ranking leaders (let's say less than 400 Elo of difference), then there are nine engines in each group (number 2 to number 10), and their average ratings are:

Code: Select all

R_A = <Rating &#40;1A&#41; | &#123;without Komodo,    rating&#40;i&#41; > 2958&#125; ~ 3115.3 Elo.
R_B = <Rating &#40;1B&#41; | &#123;without Stockfish, rating&#40;i&#41; > 2940&#125; ~ 3093.7 Elo.

Rating &#40;Komodo&#41;    - R_A ~ 242.7 Elo.
Rating &#40;Stockfish&#41; - R_B ~ 246.3 Elo.

I would not call that a significant difference.

I hope the version of Andscacs running on TCEC will be like 40 elo better or more than the 3150 announced; that was of 0.85. Also I know that Nirvana will be stronger, and probably other engines in every group. So is really difficult to tell which group is stronger.

[JJJ]

Fire could be stronger that last time where it played less good than usual. But I don't have any news about it.
A strong update of Fire would make it close to Houdini 4.

Fritz 15 could replace Rybka 4.1 at some stage.

Why couldn't Rybka just be the tournament name for what is actually Fritz 15.1?

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.

Fritz 15 could replace Rybka 4.1 at some stage.

Fritz 15 could finish a respectable top-3 in any of the stages.

For the computerchess community it's much better to have a few wildcards,
which are not selected by strength, but by other criteria like stamina,
integrity and whatever, besides hunting for the biggest E.. (fill in),
which is a main reason for numerous clones and useless pseudo derivates.
