flat_crossover function

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

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 flat_crossover than the flat crossover operator is applied in the genetic search. flat_crossover draws a random number between parents' genes and returns a pair of generated offspring

flat_crossover(object, parents, ...)

Arguments

• object: A GA::ga object
• parents: Indices of the selected parents
• ...: Additional arguments to be passed to the function

Returns

List of two generated offspring

Examples

f <- function(x){ 
  return(-sum( (x-5)^2 ) )
}
myga <- ga(type="real-valued", fitness = f, popSize = 100, maxiter = 100, 
           min = rep(-50,5), max = rep(50,5), crossover = flat_crossover)
print(myga@solution)
