Naum is a computer chess engine by Canadian programmer Aleksandar Naumov. The last commercial version (4.2) was released in March 2010. The program supports both UCI and Winboard protocols and can therefore be operated under different graphical interfaces. Naum has commercial versions for single and multiple-processor systems, a freeware version (2.0, released September 2006)[1] for single-processor systems, and a version for Palm OS (1.8, released in June 2006). The latest version, 4.6, was also freeware.[2]

History[edit]

After Naum tied for first with Rybka in the 2008 Internet Computer Chess Tournament,[3] it did not compete in any other over-the-board (OTB) tournaments.[4] In early 2009, Naum attained second place behind Rybka on chess engine rating lists, such as CCRL[5] In 2012, the development of Naum was discontinued,[6] and it has since only had minor updates. In 2013, Naum participated in the Thoresen Chess Engines Competition and the author released a software patch to enable the engine to run stably with 16 processors.[7] Finally the author released it as freeware.[2]
