Somehow a leela style net that never saw positions with more than 18 pieces was able to “memorize” opening moves. Yet somehow people arguing this tired old argument are unable to memorize this refutation. :D I'm quite sure myself and others have pointed out the logical flaw in this reasoning, yet y...

Decided it was an appropriate time for release. Changes since 2.0: Various bugfixes mostly due to members of the community pointing out usage issues to me. Some minor eval smoothing (simple linear interpolation between previous value). Introduction of NNUE. For now, NNUE is either on or off, there i...

Downloading a network file and installing it is the exact same process as downloading an engine and installing it.

Apparently, the first time is quite easy, but the second time is exceedingly difficult....

Lol.

I agree that in general it is solution for a problem which doesn't really exist (much like hybrid eval). It wastes bandwidth, storage space, and even makes things more cumbersome in some situations. For example, say you wanted to use an old net with a new compile. You have been using the (old) baked...

I doubt it would make that big of a difference really. There is one very small change I would make to nodchip's repo for the training data gen. Maybe I will submit a PR.....

I've pushed the upstream merge to Crystal. Instead of a bool for NNUE, it has off, hybrid, and on as choices. I *think* everything is working fine, but haven't really had the time to go over all the changes closely. Planning on doing a 3.0 release in a couple of weeks, but the impatient can just com...

Lol, well.... there won't be any of that in Crystal, or at the very least there will be an option to just use the NN.

If what people are after is relatively strong low depth play, they are more than welcome to use Crystal. Free of charge....

I think this is likely just a pruning issue deep in the tree, which can happen especially with relatively narrow & deep winning paths.

Reductions are just incredibly strong regardless of root depth.... and when things get reduced beyond a certain point things can go a bit sideways.
