Genetic Algorithms 23/30: Swap Mutation with Java Implementation

SpletA random swap mutation will choose randomly 2 genes from a given tour and swap them around. This is the kind of mutation that most closely resembles a typical genetic algorithm mutation. random inversion A random inversion swap will choose a consecutive subset from the tour and reverse it. The size of the subset is also chosen randomly. SpletIt depends what you want to do with an index error (the swap does not exist) but this works: x = [1,2,3,4,5] def swap_numbers (li, ind): try: li [ind],li [ind+1]=li [ind+1],li [ind] except … harless y marina
