Performs linear crossover operation on a pair of two selected parent candidate solutions

Description

This function is not called directly but is given as a parameter in GA::ga function. In GA::ga, if the parameter crossover= is set to linear_crossover than the linear crossover operator is applied in the genetic search. linear_crossover generates three offspring and performs a selection mechanism to determine best two of them.

Usage

1
linear_crossover(object, parents, ...)

Arguments

object

A GA::ga object

parents

Indices of the selected parents

...

Additional arguments to be passed to the function

Value

List of two generated offspring
