Zappa-Mexico « on: Nov 29, 2012, 06:14:42 AM » I am interested any chess engine which suggest good moves in End-game.Could anyone suggest.I heard Zappa-Mexico is very strong in end-games. After a lot of googling and asking some chess computer forums, I found one called Zappa Mexico II. If you edit the settings in a GUI like Arena (provided below), it'll play some very aggressive chess and pretty fun than your standard, boring positional chess computer. Zappa Mexico II improve a lot.on 8 cpu. If i compare with my last test rybka - Zappa, Mexico II gain 39 elo!!! Competitor come more and more closer to Rybka now. We will not see no more 200 elo difference between Rybka and his closest competitor. I think soon, we will see some chess engine that could beat Rybka 2.3.2 smp.

Frank Zappa[1]

Zappa,
an UCI compliant chess program developed by Anthony Cozzie. Zappa won the WCCC 2005 in Reykjavík, and after the Rybkadisqualification 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 [2][3][4] . Zappa's book authors for different events were Arturo Ochoa (CCT7) and Erdogan Günes[5] .

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[8] .

Immediately after the successful WCCC 2005, there were plans to commercialize Zappa. First attempts with Vincent Diepeveen involved failed [9] . In April 2006 [10] , 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.

Quote from No Commercial Potential : The Saga of Frank Zappa (1972) by David Walley, p. 4 [11][12][13] :

Jawaka Information is not knowledge

Knowledge is not wisdom
Wisdom is not truth
Truth is not beauty
Beauty is not love
Love is not music
Music is the best

Board Representation

Zappa utilizes bitboards and uses rotated bitboards to generate sliding attacks on the fly. Anthony once experimented with incremental updatedattack tables, which was a win on 32-bit systems [14] .

Hash Collisions

Excerpt from The Effect of Hash Signature Collisions in a Chess Program, that is Crafty and Zappa [15] :

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 [16] .

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[17] . Zappa Mexico can be used on Windows or Linux computers with up to 512 CPU cores.

In March 2008 Anthony Cozzie announced that 'the Zappa project is 100% finished', which includes both tournaments and future releases [18] .

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 [19][20] .

-I'm trying to set up Zappa M II for analysis but it doesn't seem to respond to the uci settings. I'm assuming this means that you have to change the parameters in the zappa ini file similar to the old winboard engines. It seems to work with the hash. But what I'm wondering is if anybody can help me with the rest of the parameters. I'm more of a chess player, and less of an engine guy. Any help would be great.

- The search options are the ones I'm really concerned with. What is r4 depth, futility pruning, history pruning etc. etc.
-I also noticed in the engine that null move is on by default, whatever null move is, but in my ini file its 0 which I'm assuming means off. Anyways any help would be great.

-I'm assuming that Zappa Mexico does something like rybka to the nodes per second, because both zappa mexico, and zappa mexico II run extremely slow on my machine. 50 000 nodes per second on average. Just for a bench mark the king 3.50 runs at 150 000 nodes per sec on my machine. I'm hoping this is normal behaviour.

-I'm running outta space but one last thing........I can't find the ini file for Zappa Mexico the original can I use the same one as zappa M II. Or are there different parameters. If so can someone shoot me the ini file for the original Zappa Mexico.
