Instead, he published it firstly as an already integrated code for Stockfish chess engines. Ronald de Man did not provide the probe code as an independent library. The first one, KRPPvKRP, has a significantly higher frequency of use than the others and should be always downloaded: Bellow is the top 20 of those endgames by their order.
Syzygy endgame tablebases download#
Thus some users choose to download one or a few endgames only, based on their statistics of use in endgames. They also require a long time to download too.
Syzygy endgame tablebases full#
Users should download them in full sets (3, 4, 5, 6 men).Īll 7 men files' size is over 16.7 TiB, over storages of typical modern computers. The sizes of those men are small enough to download and store on modern computers.

There are some free FTP servers for downloading such as Bojun Guo and Lichess servers. Using his tools some people have generated endgames and published them via DVD or online.Īs of February 2015, all 3-5 and most important 6-men Syzygy Bases are commercially available on 4 DVDs by ChessBase as Endgame Turbo 4 for their products Deep Fritz 14, Komodo Chess 8, Houdini 4 or ChessBase 12/13. Ronald de Man has provided only open source code for generators/probers but not endgame files themselves.

Syzygy endgame tablebases generator#
His original generator could not create them. Generation time would be about 64 x per table, which means around 175 x time total. Ronald de Man wasn't initially interested in the creation of 7-men Syzygy Based since the generation would require about 1 TB of RAM, too expensive at that time. To generate all 6 men, it requires a system with at least 32 GB of RAM and may run in 5 days (the period was measured with a computer 6-core i3930K 4.2Ghz, 64 GB). It is multithreading and processes completely in RAM. On the first release (Apr 01, 2013) the generator was ready to generate all endgames up to 6 men. Ronald de Man estimated if keep them all, the Syzygy's 6 men size may increase 158 GB, become 307 GB in total, double on size, be 4 times as small as Nalimov 6 men. However, when all DTM EGTBs have full data of two sides, Syzygy EGTB omits data of one side for DTZ data to save space. It is 7 times as small as Gaviota for 5 men, 8 times as small as Nalimov for 6 men, 8 times as small as Lomonosov for 7 men. Syzygy EGTB is significantly smaller than any existent DTM EGTB. WDL has full data for two sides but DTZ50 omitted data of one side to save space. rtbz) with distance-to-zero information for access at the root. rtbw) storing win/draw/loss information considering the fifty-move rule for access during search, and DTZ files (extension. Syzygy Bases consist of two sets of files, WDL files (extension.
