Sol Invictus [1]
Invictus, (InvictusChess, Invictus Chess)
an UCI compliant open source chess engine by Edsel Apostol, written in C++ and licensed under the GPL v3.0, first released in September 2018 [2].
Invictus is influenced by other open source engines in particular Stockfish, Ethereal, Defenchess, and Minic concerning Texel's Tuning Method [3].
Tom Kerrigan of TSCP fame is given credit for sharing the Simplified ABDADA idea [4].
Invictus r324 had its tournament debut at TCEC Season 21 in May 2021 and gained a respectable 50% score in its strong Qualification League.
