Workflow Scheduling Using Hybrid GA-PSO Algorithm in Cloud Computing

Algorithm 3

The mutation method.

Input: offspring_chromosome   //returned from crossover operator

Output: Newchromosome

Set mutationRate = 0.5

  If (Math.random mutationRate)

    = Rand offspring_chromosome.length // select a random number

    = Rand offspring_chromosome.length // select a random number

       If offspring_chromosome [] !=offspring_chromosome[]

        Swap (offspring_chromosome [], offspring_chromosome[])

       End If

  End If
