niching {rmoo}

Niche-Preservation Operation

Description

Generation of niche, by associating reference points to population members

Usage

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

Details

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

Value

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