create_population: Create population

In MOEADr: Component-Wise MOEA/D Implementation

Create population

Description

Create a population for the MOEADr package

Usage

create_population(N, problem)

Arguments

N	population size
problem	list of named problem parameters. See Section Problem Description of the moead() documentation for details.

Details

This routine creates a population matrix for the MOEA/D. Currently only a multivariate uniform distribution is implemented. All points are created within the standardized space 0 ≤ x_i ≤ 1, i = 1,...,n_v.

Value

A population matrix X for the MOEA/D.
