EnsureBounds: Altering vector of doubles to satisfy boundary constraints

Description

Byte based crossover and mutation operators can generate variables out of bounds of the decision variables. This function controls if variables are between their lower and upper bounds and if not, draws random numbers between these ranges. This function directly modifies the argument doubles and does not return a value.

Usage

EnsureBounds(doubles, mins, maxs)

Value

Function directly modifies the argument doubles and does not return a result.

Arguments

doubles

A vector of doubles

mins

A vector of lower bounds of decision variables

maxs

A vector of upper bounds of decision variables
