to CCRL and CEGT re Komodo 13.2

We have found and fixed a problem with repeating time controls in Komodo 13.2 that was a by-product of an improvement to increment time controls. We also fixed a couple unrelated minor bugs that should have no elo effect, and made some improvements to the personalities. I'm not sure when we can rele...

Re: CEGT - rating lists October 20th 2019

Looks like something we did to improve normal (increment) play backfired for repeating time controls; we're working on it. We didn't bother to test repeating time controls for this release, apparently that was a mistake.

Re: top engines vs 2400 engine knight odds matches

You can increase your chances by setting Contempt to a high value, perhaps 100, as this encourages Komodo to avoid closed positions. Also, I don't know how many threads you can use on that hardware, but as long as it is more than 1 this will make for more varied play. You can also set "variety" to a...

Re: top engines vs 2400 engine knight odds matches

I don't know anything about that specific hardware, but since Hiarcs on a cellphone got a performance rating something like 2900 a decade ago I think it's safe to say that Komodo on a modern cellphone would be way above 2600, and a fast time limit favors the computer over the human. But you don't sa...

Re: Komodo 13.2 Release

a significant improvement in MCTS playing strength on six or more threads (we got a plus 20 elo result in 1300 bullet games on 8 threads) Why? I mean, how does a +6 on a single thread translate to +20 on 8? Why not +6 on 1 and 3 and 8 threads? I can understand that more core = more strength, but th...

Re: Komodo 13.2 Release

Larry, are you and Mark also working on a NN version? Well, we have a version of KomodoMCTS that can use and benefit from a NN, but not yet by enough to justify releasing it. If it needs a good GPU and a third-party NN, the benefit needs to be substantial. We don't yet have a decent NN of our own.

Re: Allie v0.5 released

For any given network, will it generally play stronger with Allie v0.5 or with the latest Lc0? Does it depend on the network, or on the hardware, or on the time control, or on the position? If it does depend on any of these things, which network, hardware, time control, or position type would you ex...

I see that both versions of Komodo are competing in the TCEC Cup 4 with version 2418. How close is version 2418 to the official release of 13.2? Is it weaker, stronger, or the identical version?
Identical.

Komodo 13.2 Release

We are releasing Komodo 13.2 today at komodochess.com. The two main reasons for this release are a significant improvement in MCTS playing strength on six or more threads (we got a plus 20 elo result in 1300 bullet games on 8 threads), and a new feature, "Personalities", which adds seven new playing...
