How do you retrieve the current solution from the genetic algorithm optimization?

I am currently running an optimization using SADEA on a patch antenna configuration. I am running this in the antenna designer gui and am using the gui for the optimizer as well.

I can see the population diversity dropping nicely and the convergence trend is progressing well, too; however, it has taken several days on several hundred cores and I would like to retrieve the current solution so that I do not lose the progress that has been made.

Is there a way to stop the optimization and save/retrieve the current progress/optimized design?
