Predicto is a GA market forecaster. It forecasts day-to-day changes in the S&P 500 market index. Predicto's population of 101 market forecasting algorithms has been continuously evolving since May 20, 1988. The GA (Genetic Algorithm) approach uses processes that have been observed in Darwinian evolution (such as natural selection, mutation, sexual reproduction, and genetic inheritance) to 'evolve' populations of algorithms. When the GA method is applied to economic forecasting, the algorithms evolved are market forecasting formulae.
