  abstract =     "There are two important limitations of standard
                 tree-based genetic programming (GP). First, GP tends to
                 evolve unnecessarily large programs, what is referred
                 to as bloat. Second, GP uses inefficient search
                 operators that focus on modifying program syntax. The
                 first problem has been studied in many works, with many
                 bloat control proposals. Regarding the second problem,
                 one approach is to use alternative search operators,
                 for instance geometric semantic operators, to improve
                 convergence. In this work, our goal is to
                 experimentally show that both problems can be
                 effectively addressed by incorporating a local search
                 optimizer as an additional search operator. Using
                 real-world problems, we show that this rather simple
                 strategy can improve the convergence and performance of
                 tree-based GP, while reducing program size. Given these
                 results, a question arises: why are local search
                 strategies so uncommon in GP? A small survey of popular
                 GP libraries suggests to us that local search is
                 underused in GP systems. We conclude by outlining
                 plausible answers for this question and highlighting
                 future work.",
