Size Fair and Homologous Tree Crossovers

  title={Size Fair and Homologous Tree Crossovers},
  author={William B. Langdon},
Size fair and homologous crossover genetic operators for tree based genetic programming are described and tested. Both produce considerably reduced increases in program size (i.e. less bloat) and no detrimental eeect on GP performance. GP search spaces are partitioned by the ridge in the number of program v. their size and depth. While search eeciency is little eeected by initial conditions, these do strongly innuence which half of the search space is searched. However a ramped uniform random… CONTINUE READING
