Multiobjective Prioritized Workflow Scheduling in Cloud Computing Using Cuckoo Search Algorithm

Algorithm 2 (Modified cuckoo search algorithm).

Input: Ms with their speed, bandwidth, RAM capacity

Output: Arrange the VMs based on the efficiency

Step 1: Input the VMs

Step 2: Generate the initial population

Step 3: continue till t < max generation or satisfy the stop criteria

Step 4: Get the Cuckoo randomly by using the levy fights

Step 5: Evaluate the Cuckoo fitness

Step 6: Choose a nest randomly

Step 7: if F_i > F_j then

Step 8: Replace F_j by the new solution

Step 9: end if

Step 10: Remove the worst nests and build the new nests

Step 11: go to step 2

Step 12: use genetic algorithm based cross over and mutation technique to find out the solution

Step 13: Return the order of the VMs
