Simple single point crossover and mutation. 

Simple single point crossover and mutation. 
 class desdeo_emo.recombination.SinglePointCrossoverMutation.SinglePoint_Xover(ProC: float = 1, DisC: float = 30)[source]
Simple single point crossover and mutation.
 Parameters
 ProCfloat, optional
[description], by default 1
 DisCfloat, optional
[description], by default 30
 crossover(ind_0, ind_1)[source]
Single point crossover. :param ind_0: individual_0 :param ind_1: individual_1
 Ret:
new_0, new_1: the individuals generatd after crossover.
 do(pop: numpy.ndarray, mating_pop_ids: list = None) numpy.ndarray [source]
 Consecutive members of mating_pop_ids are crossed over
in pairs. Example: if mating_pop_ids = [0, 2, 3, 6, 5] then the individuals are crossover as: [0, 2], [3, 6], [5, 0]. Note: if the number of elements is odd, the last individual is crossed over with the first one.
 Parameters:
pop (np.ndarray) – Array of all individuals
mating_pop_ids (list, optional) –
 Indices of population members to mate, by default None, which shuffles and
mates whole population
 Returns:
The offspring produced as a result of crossover.
 Return type:
np.ndarray
