abstract = "We demonstrate the effectiveness and power of the
distributed GP platform, EC-Star, by comparing the
computational power needed for solving an
11-multiplexer function, both on a single machine using
a full-fitness evaluation method, as well as using
distributed, age-layered, partial-fitness evaluations
and a Pitts-style representation. We study the impact
of age-layering and show how the system scales with
distribution and tends towards smaller solutions. We
also consider the effect of pool size and the choice of
fitness function on convergence and total
computation.",
