Winter

I intend to reuse this thread in the future for all Winter releases, as other authors have done similarly. This first post is the Winter 0.9 release post. Before I get into what has changed since version 0.9, I think it is interesting to note what has not changed. Winter is still using the exact sam...

Re: A match between SF12+NNUE and Leele ver.0.26.2

Re: "It must be a clone of some sort..."

It would not be to difficult to add a lot of ideas from Stockfish and add NNUE evaluation to pimp it up 100 or 200 Elo, but I simply don't want to do this because it would give me the feeling that it is not my own engine anymore. There is a word for this. I believe it is called "integrity." This is...

Awesome! I haven't actually gotten around to properly reading the paper, so I what a rough deadline for submitting questions could be?

Re: A match between SF12+NNUE and Leele ver.0.26.2

A tester does not need 5000 games, unless the goal is only to maximize the Elo precision. A useful tool for engine developers. What are you trying to answer. 1. What is the exact elo deference between A vs B. 2. Who is better only between A vs B, and this usually takes much fewer games to prove sta...

Re: A comparsion -Elo helps-, pieces on board, 3 ratings for 41 engines!

Nice data! It is interesting to me that Winter seems inversed. In your second post Winter goes 31->24->22->19, progressively improving ranking the later the game goes.

I am not completely sure how to interpret the data however, perhaps Winter is just slow at closing out games?

Re: AlphaBeta all returning the same number

I think given the information you have provided we cannot say for certain what is going on. It should be noted however, that there might not be anything wrong at all. I you have a fail-hard framework, then moves will not return a static score below your lower bound. This means, if you search the bes...

Re: NNUE accessible explanation

1) If I want the NN to return an evaluation, which could be used in a traditional alphabeta search engine, how is this achieved most commonly? Do I have a last hidden layer that feeds into a single output neuron which uses e.g. a tanh activation function so -1 would be a loss and +1 would be a win?...

Re: The White Room

Oh wow! Thank you! I honestly only followed the first half of the tournament and mostly followed the gauntlet after that. After a very bad start I was just happy Winter was no longer last, but I guess with how close the field was Winter was able to make a fairly extreme comeback. Thanks for organizi...

Re: Stockfish NNue [download ]

Thank you! I have an i7-9700k with 2080ti. Which version should I use? popcount, bmi2, or avx2? The GPU is irrelevant for SF. Use whichever on happens to run fastest on your system, it's not like you pay money per binary. Just run them each from a couple positions. Most likely BMI2 version will be ...
