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 arithmetic_crossover than the arithmetic crossover operator is applied in the genetic search. arithmetic_crossover generates offspring using the weighted mean of parents' genes. Weights are drawn randomly.

Usage

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 = arithmetic_crossover)
print(myga@solution)
