Pedantic - UCI engines Author: JoAnn D. Peeler
Rating Chess Engines Diary CEDR=3125
v.2.0.0:
This release replaces the HCE evaluation with a NNUE evaluation with architecture smol-net™ (768 -> 128) x 2 -> 1 and CReLu activation. I would like to thank @lithander for his inspiration for manual vectorization of both UE and activation. I also would like to thank @jw1912 for supplying and excellent training for networks. Without that I would still be working on this release. The net was trained with 400 million positions generated from Pedantic 1.1.0 self-ply and retrained using data from the initial net. While the HCE has been replaced for this release, I expect that a future release will reenable it so that the user can select between NNUE and HCE.
