  abstract =     "This paper investigates the efficiency of using
                 semantic and syntactic distance metrics in fitness
                 sharing with Genetic Programming (GP). We modify the
                 implementation of fitness sharing to speed up its
                 execution, and used two distance metrics in calculating
                 the distance between individuals in fitness sharing:
                 semantic distance and syntactic distance. We applied
                 fitness sharing with these two distance metrics to a
                 class of real-valued symbolic regression. Experimental
                 results show that using semantic distance in fitness
                 sharing helps to significantly improve the performance
                 of GP more frequently, and results in faster execution
                 times than with the syntactic distance. Moreover, we
                 also analyse the impact of the fitness sharing
                 parameters on GP performance helping to indicate
                 appropriate values for fitness sharing using a semantic
                 distance metric.",
