Population object does not have `compute_pareto_fronts` method #386

Closed Nick-Hemenway closed 4 years ago

Nick-Hemenway commented 4 years ago

I am new to Pygmo and am trying to use it for multiobjective optimization of electric machines. After creating and evolving a population, I want to extract and plot the pareto front. The documentation for the population class located here says that there is a compute_pareto_fronts method, however, when I try to do this, I get an error saying that no such method exists. I am using Pygmo version 2.12.0.

You are reading the documentation of the old pagmo 1.x project. The docs for pagmo2, which is this GitHub repo, have a different URL. You can find it on the readme of the GitHub page.

In pygmo2 plot pareto front is no longer a method of population, rather and if I am not mistaken, a stand alone function.
