Re: trying to understand mcts

Hi, As the topic says, I'm trying to understand mcts. I tried implementing it before and that did not work very well (at par with Pos :D) so my guess is that I simply have the wrong understanding of how mcts works. What I did was: - find which moves there are in the root node - pick one at random -...

Re: Komodo 13 released

What is optimal table memory settings for my system? i7-5960X 4.5GHz, 16 GB ram, M.2 SSD for 6-men. I've often used 256 MB for table memory. Opinions please. The default should be fine for Table Memory for most any game you would play. We made this an option because people doing long analysis (like...

Re: Komodo 13 released

Each MCTS tree entry is about 40 bytes, and an hour has 3600 seconds, so 1400 * 40 * 3600 is about 200 megs an hour. Sorry, Mark, but knowing this calculation already from Readme, isn't there (at Readme) one 0 missing? There's about the same example given for 8 cores and 5 hours and factor is 1000 ...

Re: Komodo 13 released

Using Aquarium GUI, after 1 minute in a typical endgame position with 6-man Syzygy installed, SF shows 45,680 kN/s and 260K TB access; Komodo shows 40,000 kN/s and 827K TB access; Komodo MCTS does not show any speed nor any TB access. Do you think that this is an Aquarium issue or perhaps Komodo MC...

Re: Komodo 13 released

All Komodo are much below Stockfish right now. Around 60 elo at very least in TCEC condition. That's what i thought. So is komodo trying to hold down the elo of its standard engine just to give time for mcts to catch up with it? I assume you were joking. No, we are not "holding down the elo" of any...

Re: Komodo 13 released

Both Hash tables are used. Hash is used by the short alpha-beta searches used to estimate winning probability and the policy (how likely a move is to be played) and MCTS Hash is used to store the Monte Carlo Tree. For regualr home machines the values should be good enough unless you plan to do very...

Re: Komodo 13 released

Thanks very much for the latest update! I've also been reading over the 7 piece EGTB updates you have supported but it will be a while till I download many of these. I upgrades to a 256 Gb USB drive recently which was enough to download all the 6 men Syzgy files but now this? :D Oh welll... Anyway ...

Thanks Larry.

Where do I set MultiPV under the Shredder GUI?
In the Deep Shredder GUI (I think they are all alike), f6 makes it analyze more lines and f5 less lines. If you right click over the game analysis/PV information, it gives a menu of options.
