in reply to Recursively-generated Iterators

Nice ++

I wonder how general your technique is - I mean is it applicable only the to computation you present, or is it generally good for all memory-eating recursive computations ? Can one formulate a general algorithm for this transformation ?

By the way, another technique to ease these computations is Memoization. It is almost always very helpful for recursive algorithms like the one you present.

    It should be applicable to any algorithm that generates a set where different portions of the set are generated by different recursive calls. That's mostly combinatorial things like this, but Towers of Hanoi would also be a good example. If each item in the returned set required some value from more than one recursive call, you couldn't do it this way.
