Komodo 13.1 released

Post by lkaufman »

Komodo 13.1 has been released at komodochess.com. It is the version that just won the World Computer Chess Championship and the World Software Chess Championship in Macao, plus some small enhancements found during that event. Unlike the past few releases, this time the improvements (since version 13.02) almost all applied to both the regular and the MCTS versions. We estimate the elo gain at fast time limits from version 13.02 to be around 20 points, for both regular and MCTS versions, and regardless of one, four, or many threads. Aside from the strength gains, we have added two new skill levels at the bottom and two new skill levels at the top, so old level 0 is now level 3 and old level 19 is now level 22, with 23 and 24 being even stronger, and 25 being unlimited. Pricing remains the same, so 13.1 is free for subscribers and 20% discounted for those who bought Komodo 12 or later version. We continue to recommend the MCTS version whenever Multi-PV is used, and for more human-like play, but the normal version remains the strongest for engine vs engine games and is the one that won the WC. We suggest that the rating groups give priority to the normal version this time, since that was the focus of our efforts since the last release, but MCTS gains should be similar.
The two biggest changes in Komodo 13.1 were probably a substantially revised King Safety, and changes to the hashing scheme. There were also quite a few changes to search, and significant re-tuning of many eval terms.

Larry, Is there Komodo for IPhone ? Thanks in advance.
I am thinking chess is in a coin.Human beings for ever playing in one face.Now I am playing in the other face:"Antichess". Computers are as a fortres where owner forgot to close a little door behind. You must enter across this door.Forget the front.

It's not out yet, but it is under development. I don't really have any idea when it will be ready.

According to the interview, the last TCEC season "ended a few days ago", with Leela winning controversially. Which season was that?! Sorry if I lost track of the TCEC seasons. :| It's not like there's a whole lot of current information on TCEC out there.

We were sent the questions at the end of May. I am not sure why the interview was not published until today.

Yes, honestly I think it was a really lame interview - the questions that is.

I have learned so much more in even a single post by Larry or Mark on this forum. :D
I suppose they had to dumb it down for the average reader so I can't blame them.

I am really enjoying using MCTS in 13.02 (needed the updated Fritz GUI) for my opening analysis. I am pretty sure I will subscribe again as a result.

Hi Larry & Mark,

Would it be possible to provide a Raspberry Pi Binary to try say Komodo v10 on Picochess & the DGT Pi?

Thanks,

Al.
