  abstract =     "This paper investigates the impact of geometric
                 semantic crossover operators in a wide range of
                 symbolic regression problems. First, it analyses the
                 impact of using Manhattan and Euclidean distance
                 geometric semantic crossovers in the learning process.
                 Then, it proposes two strategies to numerically
                 optimise the crossover mask based on mathematical
                 properties of these operators, instead of simply
                 generating them randomly. An experimental analysis
                 comparing geometric semantic crossovers using Euclidean
                 and Manhattan distances and the proposed strategies is
                 performed in a test bed of twenty datasets. The results
                 show that the use of different distance functions in
                 the semantic geometric crossover has little impact on
                 the test error, and that our optimized crossover masks
                 yield slightly better results. For SGP practitioners,
                 we suggest the use of the semantic crossover based on
                 the Euclidean distance, as it achieved similar results
                 to those obtained by more complex operators.",
