History The program was developed by Igor V. Tetko with participation of  Vasily V. Kovalishyn (Cascade Correlation algorithm) during 1993-1999. It was changed to support Java interface (developed with  Dmitry Filipov) in 1999.

Software The interface for the browser is done using Java, calculations are done using C++ program.

Hardware The calculations are done on several UNIX servers.
