constraint_none {MOEADr} | R Documentation |
NULL constraint handling method for MOEA/D
Description
Construct the preference index matrix based only on performance values.
Usage
constraint_none(B, bigZ, bigV, ...)
Arguments
B |
Matrix of neighborhoods (generated by |
bigZ |
Matrix of scalarized objective values for each neighborhood and the
incumbent solution (generated by |
bigV |
Matrix of violation values for each neighborhood and the incumbent solution |
... |
other parameters (unused, included for compatibility with generic call) |
Details
This function ignores the violation values when constructing the preference index matrix, using only the scalarized performance values.
Value
[ N x (T+1) ]
matrix of preference indices. Each row i
contains
a permutation of {1, 2, ..., (T+1)}
, where 1,...,T
correspond
to the solutions contained in the neighborhood of the i-th subproblem,
B[i, ]
, and T+1
corresponds to the incumbent solution for that
subproblem. The order of the permutation is defined by the increasing values
of f(xk)
, where f(xk)
is the aggregation function value of
the k-th solution being compared.
