Description

Problem Decomposition using Uniform Design for MOEADr package

Usage

1

Arguments

decomp

list containing the relevant decomposition parameters. Besides decomp$name = "uniform", this method requires the definition of the following key-value pairs:

  • decomp$N, number of subproblems to generate. It is important to highlight that the number of subproblems must be greater than the number of neighbors declared in neighbors$T (see moead() for details).

  • decomp$.nobj: integer value, decomp$.nobj > 1. Number of objectives of the problem.

...

other parameters (included for compatibility with generic call)

Details

This routine calculates the weight vectors for the MOEA/D using the Uniform Design:
