box_constraints: Box constraints routine

In fcampelo/MOEADr: Component-Wise MOEA/D Implementation

Box constraints routine

Description

Calculates the constraint values and violations when only box constraints are present.

Usage

box_constraints(X, ...)

Arguments

X	Population matrix of the MOEA/D (each row is a candidate solution). If NULL the function searches for X in the calling environment.
...	other parameters (unused, included for compatibility with generic call)

Details

This routine calculates the constraint values and violations for a population matrix in the MOEA/D. Each row of the matrix is considered as a candidate solution. This routine expects the candidate solutions to be standardized, i.e., that the variable limits given in problem$xmin and problem$xmax are mapped to 0 and 1, respectively.

Value

List objective containing a matrix of constraint values Cmatrix, a matrix of individual constraint violations Vmatrix, and a vector of total constraint violations v.
