  abstract =     "We present a new mechanism for studying the impact of
                 subtree crossover in terms of semantic building blocks.
                 This approach allows us to completely and compactly
                 describe the semantic action of crossover, and provide
                 insight into what does (or doesn't) make crossover
                 effective. Our results make it clear that a very high
                 proportion of crossover events (typically over
                 75percent in our experiments) are guaranteed to perform
                 no immediately useful search in the semantic space. Our
                 findings also indicate a strong correlation between
                 lack of progress and high proportions of fixed
                 contexts. These results then suggest several new,
                 theoretically grounded, research areas.",
