Orion Constellation [1]

Orion,
an UCI compliant chess engine by David Carteau, written in C and first released in May 2014. In August 2020, David Carteau published results using an own AVX2 NNUE implementation, initially compatible with Stockfish NNUE nets, with a huge improvement in playing strength [2]. He has designed and trained his own NNUE-like approach published as Cerebrum open source library on GitHub [3], first used within Orion 0.8, released in December 2020 [4].
