My issue is self-evident: ?using this method resulted in a 30 fold increase in time. ?My question is why? ?If I time the individual components separately, nothing is unusual. ?My hunch is the "interaction" between the model.matrix and nsga2 methods. Any ideas on how to speed this process up, or circumvent the issue altogether?
