Hello !
> I think you remember ticket #18183, on matroid polytopes. I saw that
discussion the other day and I had to agree that it is an omission that we
have no `.independent_sets()` method.
Yepyep. Such a function will surely be useful.
> I want to optimize the running time. Maybe using
`subsets_with_hereditary_property` is a good choice for the top class
Matroids, I'll check it out.
I wrote it for situations when the function that checks if a set is a base
is very slow. It may not be very efficient in other cases, though it
definitely uses the information that the property is hereditary.
Good luck `;-)`
