Abstract

A series of measurements on factors in evolutionary processes are carried out for the application of an evolutionary algorithm, BTGP, to the problem information retrieval. A new evolutionary diagram is proposed that allows us to study the performance of, in principle, any evolutionary algorithm on a task. Taking inspiration from the HR diagram in Astrophysics, algorithms are classified using their degree of variation and the logarithmic ratio of exploitation versus exploration. The latter is measured as the inverse of the mean population fitness versus the fitness variance.
