Not that I know of, especially since this has the unfortunate drawback that you're going through the largest part of the search space first. Usually, I find that I want to do the opposite from this; go from both ends simultaneously. Hasan, if you recall that the powerset is just `yield from S choose k for k from 0 to |S|+1`, you see that that is exactly the implementation in the examples page. Best regards, Pål GD
