I have 5 objective functions and 5 variables. I am using NSGA II algorithm.
Can anybody tell me hoe to determine the initial size of population in GA?

One rule of thumb for defining the population size for MOPs with up to three objectives, is to use from 2 to 10 times the number of design variables. However in your case, being a MaOP (Many objective optimization problem, i.e. more than 4 objectives), the population size I do recommend to start with is 100, 20 times the number of variables in your problem.
