Re: Use MCTS

Dragon MCTS is mostly useful for preparing for or playing against human opponents who will not be consulting engines during play. Since it doesn't assume that it can always predict opponents' moves, but only assumes that they will be "good" moves generally speaking, it will choose moves that should ...

Use MCTS

For very deep analysis, should we be using MCTS? When should we be using MCTS?

Re: Can somebody compare the AMD Ryzen processors to the intel processors

"The large pages will be an engine UCI parameter for engines that support them."

Therefore, I can conclude that neither SF nor Dragon by Komodo support large pages>

Re: Can somebody compare the AMD Ryzen processors to the intel processors

Mike B: Mike, I was looking in my Engine Personality for SF 260221 in Aquarium running on dual Xeon system, and I did not see Large Pages options. Does that mean that Large Pages option would come up only on an AMD system? You have to enable large pages. There is information on this page about how ...

"Iif you just switch to MCTS mode now and then..."

For deep correspondence analysis (now and then) would that amount to something like 1024 MB (1 GB) for MCTS hash?

Wish list for next version of Komodo Dragon

LK, in the current version, it is cumbersome to change between checked "use MCTS" and unchecked (do not use MCTS). In my Aquarium GUI, I have to first switch to a different engine, then go into engine parameters to make the switch. It would be great if one could switch back and forth without needing...

Re: Dragon engine net

We normally use NNUE eval in Dragon, more so than Stockfish does.

LK: Thanks for clarification about NN size.
Looking at Dragon parameters, I don't see one for "use NNUE", so I don't know what you mean by "normally use NNUE eval".

Dragon engine net

Thanks for the insights. I had assumed that when it comes to neural nets, bigger is better, so that LK would soon give us huge NNs, e.g., 100MB.
