updt_standard: Standard Neighborhood Replacement Update for MOEA/D

In MOEADr: Component-Wise MOEA/D Implementation

Standard Neighborhood Replacement Update for MOEA/D

Description

Population update using the standard neighborhood replacement method for the MOEADr package.

Usage

updt_standard(X, Xt, Y, Yt, V, Vt, sel.indx, B, ...)

Arguments

X	Matrix of candidate solutions
Xt	Matrix of incumbent solutions
Y	Matrix of objective function values of X
Yt	Matrix of objective function values of Xt
V	List object containing information about the constraint violations of the candidate solutions, generated by evaluate_population()
Vt	List object containing information about the constraint violations of the incumbent solutions, generated by evaluate_population()
sel.indx	matrix of selection indices, generated by order_neighborhood()
B	Neighborhood matrix, generated by define_neighborhood().
...	other parameters (included for compatibility with generic call)

Details

This routine executes the standard neighborhood replacement operation to update the population matrix of the MOEA/D. This update routine is intended to be used internally by the main moead() function, and should not be called directly by the user.

Value

List object containing the update population matrix (X), and its corresponding matrix of objective function values (Y) and constraint value list (V).
