  Distributed Genetic Programming on the Internet used genetic programming in a Java applet to navigate artificial ants along the Santa Fe trail.

The website was removed in October, 2000, so the URL above no longer works. The project had some interesting graphics.

mid 1998 unknown unknown
  Golomb Rulers - The Search For 20 and 21!, the first Internet-based distributed project to find optimal golomb rulers (OGRs). The project found OGRs for 20, 21, 22, and 23 marks. The project tested 628 trillion nodes for the 22-mark ruler and 398 trillion nodes for the 23-mark ruler. The OGR search is continuing at May, 1999 2.5 years unknown
  Swiss Knife Software had a screen saver application which tried to solve the Eternity puzzle. stopped in July, 1999; not completed unknown not applicable
  The Internet Animation '99 "was an experimental project aimed to discover how a computer 3D animation could have been done using people from all over the world and coordinating everything using only email and a web page." You can download the movie from ifilm.

This site has a Lessons Learned page and other information for people who want to start their own animation collaboration projects.

PiHex caluclated the quadrillionth digit of Pi (which is 0). The creator of the PiHex project will soon begin more complex projects at September 11, 2000 24 months 1246/1734 (1.2 million CPU hours)
  The ECC2K-108 project solved Certicom's ECC2k-108 Elliptic Curve Discrete Logarithm challenge. April 4, 2000 4 months 1300/9500 was designed to run multiple and different types of projects. It ran a CSC decryption contest and a project to design safer storage vessels for nuclear waste. For the gamma flux project it processed almost 100 million work units. was the first project to use weekly cash giveaways to encourage participation. The project's parent company, Distributed Science, went out of business on May 24, 2001. The project shut down soon afterward. May, 2001 1 year unknown
ProcessTree Network TM
For-pay Internet distributed processing.

ProcessTree Network was the first project to offer pay for providers' spare CPU cycles. Its first (and last) paid project began the week of January 8, 2001. Selected users in certain locations with a Win32 platform and a 128 Kbit/sec or faster, permanent Internet connection could join the project. The payout was $US12.50 per month and location (that amount was divided among the systems active in each location during the month). The project's parent company, Distributed Science, went out of business on May 24, 2001 due to a lack of funding, and the project shut down on that date. May, 2001 4 months unknown
The GOLEM@Home Project The GOLEM@Home Project designed and evolved robotic lifeforms via a screensaver application. The screensaver randomly created a population of virtual robots on users' systems and then evolved them (the rule for evolution was survival of the robots who could move the greatest distance over an infinite plain). Every week or so a few of a user's robots moved to someone else's Golem screensaver and a few of someone else's robots moved to the user's screensaver (this feature could be disabled for users worried about security). The virtual robots contained design information that could be used to build actual working robots. October, 2001 1 year 30,000
