Triumviratus, a New Engine

Triumviratus has, as of this writing, come out of nowhere and taken over the #1 spot on the CCLR rating list, but only by one rating point. It is an open-source engine written in C++ by Francesco Torsello. Of course, a single point lead doesn’t mean anything and the engine has not yet completed a full compliment of what appear to be 30 games against its rivals.

According to techies it’s neural network structure (whatever that is) is highly intriguing for technical reason that are another language to me. There are naysayers though. Whenever a relatively new engine suddenly challenges Stockfish people get suspicious and label them Stockfish clones.

My only interest is how it performs on my laptop. To be honest, I have “tested” some engines other than Stockfish (e.g. Reckless, Swordfish and PlentyChess) in correspondence play against a few ICCF titled players and haven’t really found much of a difference...all the games ended in boring draws, even a couple in which I played the Smith-Mora Gambit against the Sicilian (1.e4 c5 2.d4).

The above tournament was held on my laptop with a time limit of 2 minutes + 2 seconds per move and the result seems to support the claim that it’s irrelevant which engine you use for your analysis, the results will be pretty much identical. Download Triumviratus from github HERE
