Non-uniform Mutation
Description
The nunimut operator is a mutation operator that adjusts for generations by reducing the mutation severity according to genetic progression (Michalewicz, 1994).
This operator is used for value encoded (integer or real number) chromosomes.
Usage
nunimut(y, lb, ub, g, gmax, mutb, ...)
Arguments
y |
A vector. Chromosome of the offspring |
lb |
A vector. Lower bounds of genes |
ub |
A vector. Upper bounds of genes |
g |
Current generation number. |
gmax |
Maximum generation number. |
mutb |
An exponent parameter that sets non-uniformity |
... |
Further arguments passed to or from other methods. |
Value
mutant |
A vector. Chromosome of the offspring |
mutgen |
The number of the mutated gene. |

Examples
lb = c(2, 1, 3, 1, 0, 4)
ub = c(10, 15, 8, 5, 6, 9)
offspring = c(8, 6, 4, 1, 3, 7)
set.seed(12)
nunimut(offspring, lb=lb, ub=ub, g=1, gmax=100, mutb=0.5)
set.seed(12)
nunimut(offspring, lb=lb, ub=ub, g=50, gmax=100, mutb=0.5)
