Permutation-specific genetic operators (mutations and crossover).

Functions

invert_mutation(population_array, fitness_array)	Reverse the order of a random contiguous segment in each individual.
order_cross(population_array, fitness_array)	Order Crossover (OX) for permutation chromosomes.
order_cross_single(vector1, vector2[, rng])	Core OX operation for a single pair of parents.
permute_mutation(population_array, fitness_array)	Randomly permute N components of each individual.
pmx(population_array, fitness_array[, ...])	Partially Mapped Crossover (PMX) for permutation chromosomes.
pmx_single(vector1, vector2[, rng])	Core PMX operation for a single pair of parents.
roll_mutation(population_array, fitness_array)	Cyclically shift (roll) a random segment of each individual.
