Hello respected researchers, First of all thanks a lot
please open the attached file researchgate.png
I am working on workflow scheduling in cloud computing using optimization technique.
In optimization every solution is just a particle.
In our case a particle is an array of 1* number_of_task.
indexes of array represents the task_number and corresponding array value represent Vm_number on which task is assigned( assume 6 task and 4vms).
now my question is if i use PSO algorithm for updating the particle of population. It may possible array value is negative, that is unwanted because a virtual machine number can't be negative. please resolve my problems .
thanks a lot
Hi Satya Deo Kumar Ram
in all optimization technique has Var-min and Var-Max, you can control theses Parameter(Var-min and Var-max).
in workflow scheduling in cloud computing with 5 task and 4 Vms, you have particle 1*5(number Task) with number Vms.
Var-min=1;
Var-max=4........number_Vms;
so particle should fill between 1 and 4(number_Vms);
if you have negative number in particle, i should use bound function.
