  abstract =     "Crossover in Genetic Programming is mostly a
                 destructive operator, generally producing children
                 worse than the parents and occasionally producing those
                 who are better. A recently introduced operator,
                 Context-Aware Crossover, which implicitly discovers the
                 best possible crossover site for a subtree has been
                 shown to consistently attain higher fitnesses while
                 processing fewer individuals.

                 It has been observed that context-aware crossover is
                 similar to Brood Crossover in that multiple children
                 are produced during each crossover event. This paper
                 performs a thorough analysis of these crossover
                 operators and compares the performance of the two and
                 demonstrates that, although they do work similarly,
                 context-aware crossover performs a far better sampling
                 of the search space and thus performs much better.

                 We also demonstrate that context-aware crossover
                 benefits from a speed up of almost an order of
                 magnitude when using a simple and very small cache,
                 which is over two orders of magnitude smaller than
                 caches typically used.",
