  abstract =     "This chapter proposes a generic framework to build
                 geometric dispersion (GD) operators for Geometric
                 Semantic Genetic Programming in the context of symbolic
                 regression, followed by two concrete instantiations of
                 the framework: a multiplicative geometric dispersion
                 operator and an additive geometric dispersion operator.
                 These operators move individuals in the semantic space
                 in order to balance the population around the target
                 output in each dimension, with the objective of
                 expanding the convex hull defined by the population to
                 include the desired output vector. An experimental
                 analysis was conducted in a testbed composed of sixteen
                 datasets showing that dispersion operators can improve
                 GSGP search and that the multiplicative version of the
                 operator is overall better than the additive version.",
