Re: TCEC season 13, 2 NN engines will be participating, Leela and Deus X

How come Hannibal is playing in Div 2? I thought it crashed out of it last season. You might be thinking of Chiron. It crashed 3/5 games in Div 1, demoting to Div 2. Div 2 had 5 of the 8 entrants losing from crashes, but none out by the three-strike rule, so I think they demoted the two worst perfo...

Re: Komodo 12.1

My understanding is that komodo MCT is a derivative of classic Komodo. I do not understand how people can think different when probably more than 90% of the chess code is the same. Note that I have no problem if tournaments allow derivatives to compete. It may be a "derivative" in a very broad sens...

Re: Komodo 12.1

We have not discussed entering multiple versions yet. Some might find it unfair. Back in the past at the World Micro Computer Chess Championship, companies would enter multiple identical chess machines to better the chance of coming in first. But we have noticed Komodo MCTS really beats up on weake...

Re: Komodo 12.1

I just have to ask: are there perhaps plans to enter Komodo MCTS into TCEC 13? My understanding is that TCEC rules would actually permit entering both classic and MCTS versions of Komodo, as the two are fundamentally different, i.e. the MCTS version can not be considered a "derivative" of classic Ko...

Re: better swiss system software question

The problem with the swiss system is that the ranking at the middle of the table is sometimes not fair and 2.5 points against strong opponents out of 6 may be worth more than 3 points against weak opponents. How about the accelerated Swiss? It tends to initially pair strong players with other stron...

Re: Alpha Zero vs Stockfish 8 tournament conditions.

I still think that calling the weights of the NN an "opening boook" is kinda misleading. It is not an opening book as you would think of one Why, when NN evaluation function is exactly what an opening book gives you - for a given position a probability of selecting each move and wining probability ...

Re: Alpha Zero vs Stockfish 8 tournament conditions.

1 Google TPU is around 50W, basically you have them 4 and another Haswell to run actual MCTS on those so around 300W. SF's hardware was most probably two 32 core CPUs each at 150W, so around 300W also. However, even they were on the same wattage, problem is Alpha0 was running on specialized hardwar...

Re: Alpha Zero vs Stockfish 8 tournament conditions.

to make it more practical: i want to know the price of 64core st hardware and the price of alpha zero hardware pls anyone? to make a more fair comparison Price would, of course, be a good criterion for comparison, but from an engineering standpoint it would be interesting to compare power consumpti...

Re: TCEC Season 10 announced

I hate to state the obvious, and all this is not new, but... What is the benefit of having a 44-core machine rather than a 24-core machine? 15 Elo, perhaps? It's not only that engines do not play significantly better - I'm sure many play worse with 44 cores. (And the developers have little chance of...
