Komodo 13.2 Release
Posted: Wed Oct 16, 2019 6:27 pm
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 styles to the normal, default personality. These are intended to simulate various types of human players, one of which, "human", is a simulation of a human grandmaster or at least someone taught by one. These personalities can be used with either MCTS or with the reduced skill levels, but not with both. Most of the personalities will play a level or so weaker than normal against engines, so they are not intended for that use, but some (especially "human") may prove tougher for some human opponents than the default personality at the same level.
The normal (non-MCTS) version is about six elo stronger than 13.1 on one thread at 2' + 1" according to our testing, as is also the MCTS version on four threads. Normally we don't release a new version with just single-digit elo gains, but the larger gain on 8 thread MCTS and the new personalities justified the release. While of course we welcome testing on both versions by the testing groups, we especially would like to see MCTS testing on 8 threads or more since that's where the significant improvement shows up.
The MCTS version is especially recommended for use with Multi-PV and for more human-like play and analysis. Its strength against human play was shown when it became the first computer in history to defeat a chess master in a rapid, (not blitz), (15' + 10") match despite giving knight odds, by an amazing 6 to 0 score! The normal version is still objectively the strongest version when Multi-PV is not in use, at least against other engines.
As usual, Komodo 13.2 is free for subscribers, and discounted 20% for anyone who bought Komodo 12 or later version.
