I have been trying to build a chess engine for a variant of chess called Monster Chess, in which white starts with just a king and 4 pawns but has two moves for every move black has - I posted about that here, if you are interested ( link ). In any case I have been trying to implement simple bitboa...

I got that a little bit later. One needs to scale the engine specific score to a win percentage sigmoid for a 0-1 or -1,0,1 range.
Similar to TD(λ) one may even try to interpolate the final result into that score. I don't know whether this was tried before.

Hello everybody, currently some threads for tuning are ongoing. Here is another question i am interested in. When creating the training data it wouldn't be a big deal to use a trainer (any engine) that computes a score for each of the positions and stores them. Instead of computing the error with t...

I was very interested in how the NNUE is actually designed an implemented. Yu Nasu originally introduced it in his 2018 paper "Efficiently Updatable Neural-Network-basedEvaluation Functions for Computer Shogi" (available here https://www.apply.computer-shogi.org/wcsc28/appeal/the_end_of_genesis_T.N...

While doing a lot of branchless avx2 computation versus all the conditional GP stuff of a classic eval - I would expect a decrease from HT improvement. Afaik HT profits most if threads have stalls due to branch misspredictions, dependency or cache misses, since the other hyper thread can keep the pi...

Hi Maksim,
i will forward your message to the site admin.

Hi Gerd, the best what I found ... An opening book (literature) about B01. The author of the book (a Grandmaster) wrote to line x ... balanced, a bit better for white. And wrote to the same line (after move transposition) in the same book a bit later ... clear better position for white. But I like ...

Note that many such collections are inaccurate. I see games posted that have ECO classifications not even close to right. But even with the best kind of database, the classification system has some ambiguities. For example, the Semi-Tarrasch (D41/D42) has a lot of lines that overlap the Caro-Kann (...

What do the latest ARM CPU with AI acceleration offer in comparison? ARM has Advanced SIMD aka NEON , a combined 64- and 128-bit SIMD instruction set. But NEON is old. I heard that AI acceleration in recent ARM flagships especially in Huawei's Kirin are being showcased with far leading benchmarks i...
