Dragon Human Personality

[CornfedForever]

The difference between 1300 and 1000 is negligible at that level - games filled with mistakes with the last person to make the biggest mistake losing. A human playing a little with a little study can make 1300 easy. Give him Capa's Fundamentals and he will be there in no time and fully begin to enjoy your present. My 2 cents.

He already study Bobby Fisher teaches chess
and Chess For Dummies By James Eade , and Capa's Fundamentals, but he is still rated only 1025, the problem is that he live in an area where there are lots of old players that are actually rated about 200 to 300 rating points below their actual strength and in a little town that keep him in such low rating, he is only 11 years old and an excellent student with mostly A's but his rating is stuck at 1025

I was playing around with the Human personality of the Dragon engine (in MCTS mode). Why are the evaluations so exaggerated? For example for the Scandinavian 1. e4 d5 I get +1.6. And then when I take 2. exd5 the score drops to around 0. Is this normal? Also, how realistic is the Human personality actually?

The personalities (such as "Human") use non-standard parameter settings, in particular "Human" uses a high Contempt setting (you might say it is emulating a conceited or cocky human, not an average one!). So it thinks White is much better than his real advantage when it is White, and it thinks Black is much better off than in reality when it is Black. Note that the personalities don't use NNUE ("dragon mode") since they depend on parameters that are not used by NNUE. The personalities came before NNUE; in my personal opinion NNUE already plays more like a human than the Human mode does, because it plays by patterns somewhat like humans do. Also MCTS mode makes it even more like a human as the search does not assume that it can always predict the opponent's reply. But the Skill levels don't work with MCTS, something we can address in the future perhaps.

Regarding this, does MCTS mode work properly at fixed depth, as a GUI option? If it does, that actually combines MCTS and skill levels.

No, depth is not a real figure for mcts, we just use a function of the mcts node count to display. We could define levels by this function, but even a one mcts node search would play in or near GM level, so this isn’t suitable.

I purchased Dragon 3.2 for my nephew yesterday, and he asked me today why the Minimum Elo is NOT as low as 1000, he just started to play chess 3 months ago, but the Minimum Elo that you can set Dragon is = 1320 which is too high for him

I verified that Dragon 3.2 Elo can be set as low as 1 on my Windows laptop (using chessbase gui). We would never set it to 1320, which is above the average chess.com rating! Perhaps the 1320 figure is set by whatever GUI you are using, it is not a Komodo minimum.
