Hi all,
Is there a way to generate permutations of large arrays of sizes say,in the
hundreds, faster than in the time itertools.permutations() can return?
When dealing with large loops like that (or even permutations of 50,
which is also gy-normous [1]), you have to consider what work you plan
to do in the loop.
Even if the generation were instantaneous, you still presumably are
going to have some code in the loop.
If you expect to do it on a set of 50, you're going to have to narrow
down the possibilities with some approach other than brute force.
What's the problem you were hoping to solve in the next trillion years?
