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...

Re: Possible highest rated players of all time list.

Karpov defeated Annand in a Championship match so there is a discrepancy right there. There is no discrepancy, actually. The quote says: "These models can then be used to compute the win/draw/lose probability for any given match between two players." So, all outcomes of a match are possible - inclu...

Re: Cursed win at TCEC

you said yourself: by assigning the outcome that is likely to happen should the game continue ; should the game have continued, unlimited by any specific rules, most likely SF would have won the game; indeed, such endgames are very easy to win for modern top engines. But that is true only if "unlim...

Re: Cursed win at TCEC

So, I do not see a reason to change anything: bug or not bug, the end position is simply won for white and the GUI took the rigth decision, even if involuntarily. From www.thefreedictionary.com: adjudicate - (Chess & Draughts) (tr) chess to determine the likely result of (a game) by counting relati...
