Extrema Selection : Accelerated Evolution on Neutral Networks

  title={Extrema Selection : Accelerated Evolution on Neutral Networks},
  author={Terry W Stewart},
A new modification to the genetic algorithm is presented which is specifically designed to increase the rate of evolution on fitness functions with high degrees of neutrality (mutations that do not change the individual’s fitness). Instead of allowing random genetic drift to occur when most of the population has reached the same fitness, the “reproduction fitness” of individuals is set to their distance from the population centroid. This has the theoretical effect of spreading the population… CONTINUE READING
