I use gamultiobj to do a multiobjective optimization. It is possible to see the changes of parato front graphically in each iteration through the option setting. I can see the final pareto set, variable set and population of all the variables at the end of optimization. However, I want to save the population set and pareto solution set over each iteration over the optimization. In my problem I use population size 50 for 12 variables. Please help me on this.

You can use a custom output function, as in this example, to record the population and Pareto front. In the State Structure, the Pareto front is the set of individuals of rank 1, I believe.

Please look at the link to the State Structure in my previous answer. You will find that gamultiobj passes a state structure that has the information you are looking for to a plot function or output function. Use the plot function or output function to record whatever you want to variables in your workspace, as in the example in the link in my previous answer for recording the history.
If I have answered your questions, please Accept the answer.
