WebJan 24, 2012 · One can generate points of the Pareto front in two ways: increase the population size n or run the program a few more times. Through simulations, we found that increasing n typically leads to a longer computing time than re-running the program a few times. This may be due to the fact that manipulations of large matrices or longer vectors ...
