We recently solved the two spirals problem, a di cult neural network benchmark classi cation problem, using the genetic programming primitives set up by [Koza, 1992]. Instead of using absolute tness, we use a relative tness based on a competition for coverage of the data set. This is a form of co-evolutionary search because the tness function changes with the population. Because niches are opened by proportionate reproduction, rather than crowded out, and because of the crossover operator, we… CONTINUE READING
