ChessBrain logo ChessBrain "seeks to create a massive chess playing computer by utilizing the idle processing power of networked machines." This project is an experiment "to allow internet-connected computers to work together to play a game of chess." On December 17, 2002, the project completed its first distributed game of chess without human intervention. The project's current record of total active machines, set on January 30, 2004, is 2,070.

Stage one of the project completed on August 9, 2002. 63,261,631 jobs were completed by 265 Peernode operators for this stage.

Stage two of the project began on March 1, 2003.

"On January 30th 2004, ChessBrain became the first distributed network to play a game against a single human opponent and earned an official Guinness World Record for 'the largest networked chess computer' in history!" 2,070 machines from over 50 countries competed against one chess Grand Master. The game ended in a draw. As of September 1, 2004, this record is an official 2005 Guiness World Record for "The World's Largest Networked Chess Computer."

The project software is available as a GUI client for Windows and as a command-line client for Windows, Linux, Mac OSX and FreeBSD. Version 3.0126.02 of the Windows graphical client is available as of January 26, 2004. Version 3.0129.01 of the Linux command-line client is available as of January 29, 2004. Version 3.0124.01 of the Mac OSX command-line client is available as of January 24, 2004. The Linux client can be run on FreeBSD (if you have Linux binary compatibility loaded under FreeBSD).

Chess960@home Help Chess960@home use distributed computing to play Chess 960, a variant of traditional chess in which "the initial configuration of the chess pieces is determined randomly: that means that the king, the queen, the rook, the bishop and the knight are not necessarily placed on the same home squares." This variant has 960 possible starting positions. The project is in the alpha phase of testing as of June 28, 2006.

The project added its 3000th game to its database on September 24, 2006.

The project uses the BOINC computing platform. See the BOINC platform information for the latest version of the BOINC client.

Eternity2.fr Help Eternity2.fr solve the Eternity II puzzle and win a prize of US$1,000,000. Note that to participate in this project you must purchase an Eternity II puzzle and create some piece definition files to prove you own the puzzle. US$2,000,000 will be awarded to the person who solves the puzzle. If this project solves the puzzle, the project owners will split the prize 50/50 with the project participant who finds the solution.

On January 15, 2009, the project announced that, although the puzzle remains unsolved, Tomy has awarded a US$10,000 runner-up prize to Anna Karlsson from Lund in Sweden for the highest-scoring nearly-solved puzzle submitted so far. Anna placed all 256 pieces so that the colours and patterns matched in 467 out of 480 possible places on the Eternity II board. The US$2,000,000 prize is still available as of March 30, 2009.

To participate in the project, follow the instructions on the download page. Version 2.2 of the application is available for Windows and Linux as of March 25, 2008.

Help the Optimal Solution Finder find optimal solutions for various puzzle games:
The CCL Game "A viral game made by Kerb to advertise the company CCL Computers. ... The game is based on The Incredible Machine. The object of the game is to move packages across a warehouse to the exit by placing conveyor belts, fans, and springs on a grid. The CCL Game contains 7 levels. The game ends if a level has not been solved after 10 attempts."
The CCL Winter Game Similar to The CCL Game.
Puzz Pinball  
Sony Pinball  
This project uses efficient searching algorithms to find optimal solutions to games "which have a finite number of solutions and for which source code is available. A solution is optimal if it uses the least number of objects required to find a solution."

To participate in the project, download a distributed.zip file from the project web page, then unzip the Project folder and run distributed.exe. You can specify a username and a team name if you wish to track your stats on the project website. You can run multiple copies of distributed.exe if your computer has more than 1 processor. The program will only use idle CPU time. When the program finishes testing a set of combinations, it will send the results to this server and request a new set. Version 1.3 and later of the program will automatically update itself for future version updates. Version 2 and later of the program will not automatically exit if it can't communicate with the project server. Version 1.3 and later also automatically runs on all available CPUs on your system. Version 2.0 of the client software is available as of July 16, 2009.

The CCL Game and The CCL Winter Game: 278 optimal solutions found for 32 of 34 levels;
Puzz Pinball and Sony Pinball: 847 optimal solutions have been found for 28 of 36 levels

Help the Online Life-Like CA Soup Search find "interesting patterns in Life-like cellular automata by watching the evolution of random initial configurations (known as soups). In particular, random soups are evolved until they stabilize, and all the resulting stable patterns are uploaded to the server and catalogued. If the initial soup lived for an exceptionally long time then it is also uploaded to the server."

To participate in the project, follow the instructions on the download page. In particular, you need to download and install the Golly Conway's Game of Life simulator, download and install a specific version of Python, and download and install the project's soup_search.zip Python script to run in Golly. The script prompts you for a username to display on the project website and your email address (which is not displayed).

The project is conducting several different census projects:
Conway's Game of Life
B35/S23
B36/S125 (2x2)

sudoku@vtaiwan Help sudoku@vtaiwan find more efficient techniques for solving Sudoku puzzles. Currently the project is attempting to find a solution to a 16-clue puzzle (for which no known solution exists). Gary McGuire, a professor at the National University of Ireland, has proposed an algorithm for solving a 16-clue puzzle and a program called Checker to test the algorithm on a puzzle. His algorithm is estimated to solve a 16-clue puzzle in about 300,000 years on a single CPU (using estimates based on computing power when the project began). The coordinators of sudoku@vtaiwan have created a new algorithm which may solve a 16-clue puzzle up to 128 times faster than Dr. McGuire's algorithm, in about 2,417 years on a single CPU. The algorithm can be tested much more quickly in a distributed computing project. This project is part of the V-Taiwan (or Volunteer Taiwan) project, funded by the National Science Council (NSC) of Taiwan. The project uses volunteer, distributed computing to research computer game applications.

The project uses the BOINC computing platform. See the BOINC platform information for the latest version of the BOINC client. See the project's Applications page for the latest applications and versions.
