abstract = "The relationship between search space, distances and
genetic operators for syntactic trees is little
understood. Geometric crossover and geometric mutation
are representation-independent operators that are
well-defined once a notion of distance over the
solution space is defined. In this paper we apply this
geometric framework to the syntactic tree
representation and show how the well-known structural
distance is naturally associated with homologous
crossover and sub-tree mutation.",
