Class RealMutationOp

java.lang.Object
  ga.core.goperators.ProbabilityOp
      furny.ga.operators.RealMutationOp

All Implemented Interfaces:

IGeneticOp, IMutationOp<FurnLayoutIndividual>

public class RealMutationOp
extends ProbabilityOp
implements IMutationOp<FurnLayoutIndividual>

The real mutation operator mutates genes randomly. Every single gene has a mutation chance given by the mutation probability.
