Factory function that creates normal mutation function

Source: R/mutation.R
rtnorm_mutation.Rd

Given the domain bounds and standard deviation returns a function compatible with GA interface that performs a mutation on the given individual using truncated normal distribution.

Usage

rtnorm_mutation(lower, upper, sd)

Arguments

lower

  • Lower bound of the problem's domain

upper

  • Upper bound of the problem's domain

sd

  • Standard deviation of the truncated normal distribution used for the mutation

Value

Function that takes two parameters (the GA object object

and an individual to perform the mutation on parent) and returns a new individual that is the result of normal mutation applied to the parent.

Examples

mutation <- rtnorm_mutation(
  lower = rep(-500, 5),
  upper = rep(500, 5),
  sd = rep(50, 5)
)
