distributed.net believes in the capability and potential of distributed computing. Their mission consists of three interdependent goals: development, deployment, and advocacy, to be pursued in the advancement of distributed computing. They advocate distributed computing, by encouraging global participation and contributions of processing power, bandwidth, and expertise; by providing a forum for discussion; and by raising awareness on the Internet and in the mainstream. RC5-72: Having successfully completed RC5-56 and RC5-64, they intend to also pursue RC5-72 and conquer it as well. Optimal 24 and 25 Mark Golomb Rulers: Essentially, a Golomb Ruler is a mathematical term given to a set of whole numbers where no two pairs of numbers have the same difference. An Optimal Golomb Ruler (OGR) is just like an everyday ruler, except that the marks are placed so that no two pairs of marks measure the same distance. OGR's have many uses in the real world; for more information about them and the status of the project, please visit their pages devoted to the OGR effort.
