niching function

Niche-Preservation Operation

Generation of niche, by associating reference points to population members

niching(pop, n_remaining, niche_count, niche_of_individuals, dist_to_niche)

Arguments

• pop: Last Front Population
• n_remaining: Number of points to choose
• niche_count: Niche count of individuals with the reference point
• niche_of_individuals: Count of the closest reference point to the last front objective values
• dist_to_niche: Distance between closest reference point to last front objective values

Returns

Returns the association of reference points to each individual in the population.

Details

Niching procesure is a algorithms proposed by K. Deb and H. Jain in 2013.
