  abstract =     "This paper proposes a new type of mutation operator,
                 FEDS (Fitness, Elitism, Depth, and Size) mutation in
                 genetic programming. The concept behind the new
                 mutation operator is inspired from already introduced
                 FEDS crossover operator to handle the problem of code
                 bloating. FEDS mutation operates by using local elitism
                 replacement in combination with depth limit and size of
                 the trees to reduce bloat with a subsequent improvement
                 in the performance of trees (program structures). We
                 have designed a multiclass classifier for some
                 benchmark datasets to test the performance of proposed
                 mutation. The results show that when the initial run
                 uses FEDS crossover and the concluding run uses FEDS
                 mutation, then not only is the final result
                 significantly improved but there is reduction in bloat
