Abstract

we examine the behaviour of the uniform crossover and point mutation GP operators on the even-n-parity problem for n = 3, 4, 6 and present a novel representation of function nodes, designed to allow the search operators to make smaller movements around the solution space. Using this representation, performance on the even-6-parity problem is improved by three orders of magnitude relative to the estimate given for standard GP.
