Robert Houdart on the origins of Houdini in CCC, J From the start I have very clearly acknowledged the different sources of inspiration for Houdini ( Ippo/Robbo, Stockfish and Crafty) and have shown every respect for the hard work of others, be it on my web site, in the readme file, or in this forum.

Other programmers and forum members raised suspicions that Robert took ideas from the controversial Ippolit/Robbolito source code too literally as initial base of his program. Robert Houdart claims his engine is original, and admits taking ideas from the open source programs Ippolit/ Robbolito, Stockfish and Crafty. Houdini 6.03 won the TCEC Season 10 Superfinal versus Komodo 1970.00, a successor of Komodo 11, with 53 - 47 (+15=76-9). Released in September 2017, Houdini 6 again improved in search and evaluation to add another 50-60 Elo in strength, which roughly corresponds to doubling the computational power of the computer. But that was apparently not enough for Stockfish 8 in long time control matches - Houdini 5 lost the 100 game Superfinal with 45½ - 54½. The final release version of Houdini 5 is about 30 Elo stronger than the engine that played in the TCEC tournament so far.

Houdini 5 Pro supports up to 128 threads, up to 128 GiB of hash memory, large memory pages, NUMA-architecture, and Nalimov tablebases to find the shortest path to mate.Ī development version of Houdini 5 qualified for TCEC Season 9 Superfinal, and even won the TCEC Season 9 Rapid tournament. It has a completely rewritten evaluation with more aggressive king safety and sophisticated piece mobility, features a more selective search, exploring critical variations significantly deeper, and for hardware with multiple processors, Lazy SMP. Released about three years after the previous version, in November 2016, Houdini 5 is vastly improved being about 200 Elo stronger than Houdini 4. Houdini 4, released in November 2013, was about 50 Elo stronger than its predecessor, and features 6-men Syzygy bases. Since November 2012, Houdini 3 is available as ChessBase engine. If a different move becomes best at very high search depths at the root, re-searches to determine its exact score and the new principal variation are done faster due to a reduced search depth, presumably in conjunction with extensions along the PV. According to its author, Houdini 3 applies a accelerated principal variation search, also dubbed "Smart" Fail-High. Houdini 3, released in October 2012, has further improved by more than 50 Elo points.
