I started writing my first go program I think in 1981 or '82. It was influence based and I threw it away and started over with something that did tactical search instead, in '82 or '83. I think its first tournament was in 1984, and I started selling it in 1986 (as Cosmos). It was renamed Many Faces of Go for Windows 95 I think. Through version 11, 2002, it did a simple 1 ply search with quiescence. I took some time off to write a chess program and an arimaa program to get familiar with modern alpha-beta search, the wrote an alpha-beta full board search for version 12. I was close to releasing it when Crazystone won the UEC cup last December. Starting early this year I wrote a UCT/MC engine, then added Many Faces' knowledge to it, then made it scale SMP and MPI so I could use 32 cores at the ICGA contest.
Version 12 still has the alpha-beta searcher for levels from 19 kyu to 5 kyu. The UCT engine is 2 Kyu, but it plays some strange moves, and can't explain its reasoning. So it's good to keep the old engine for weaker players.
