Zappa

a world class UCI compliant chess program developed by Anthony Cozzie. Zappa won the WCCC 2005 in [|Reykjavík], and after the Rybka disqualification in 2011 the WCCC 2007 in [|Amsterdam], the DOCCC 2005 and CCT7.During the [|World Chess Championship 2007] in [|Mexico City], September 2007, Zappa played a match versus Rybka and scored 5.5 / 10 to win the match. Zappa's book authors for different events were Arturo Ochoa (CCT7) and Erdogan Günes. || toc =Photos= =Genealogy= Zappa is not directly named for Frank Zappa, but from a scene from [|Austin Powers 2], where [|Dr. Evil's] base in the moon is divided in two units: Moon Unit Alpha and Moon Unit Zappa - the latter being the name of Frank Zappa's daughter, [|Moon Unit Zappa].

=Strictly Commercial= Immediately after the successful WCCC 2005, there were plans to commercialize Zappa. First attempts with Vincent Diepeveen involved failed. In April 2006, a commercial version dubbed **Zap!Chess** running under the Fritz GUI was released by ChessBase. The version which played the Rybka match, Zappa Mexico, is distributed by Stefan Meyer-Kahlen.

=Program Internals=

Board Representation
Zappa utilizes bitboards and uses rotated bitboards to generate sliding attacks on the fly. Anthony once experimented with incremental updated attack tables, which was a win on 32-bit systems.

Hash Collisions
Excerpt from //The Effect of Hash Signature Collisions in a Chess Program//, that is Crafty and Zappa :

||

Singular Extensions

 * Zap!Chess**, the commercial ChessBase version, has an implementation of Singular Extensions, the famous Deep Blue search algorithm. They are disabled by default, but they increase the tactical strength of the program at the cost of positional strength.

Parallel Search
Zappa was designed to run on multiple processors and massive parallel systems using shared memory and threads and has an efficient parallel search. Zappa Mexico can be used on Windows or Linux computers with up to 512 CPU cores.

=100% Finished= In March 2008 Anthony Cozzie announced that "the Zappa project is 100% finished", which includes both tournaments and future releases.

=Rondo= In 2010, Zach Wegner started to work with Anthony Cozzie, who, still in computer chess retirement, has given control for further development of his massive parallel program, now called Rondo, to Zach.
