Is this problem solvable in polynomial time?
You might be able to get a reasonable solution using loopy belief propagation' approaches (its sometimes also called generalized belief propagation', see en.wikipedia.org/wiki/Belief_propagation). As far as I know, these are approaches to solving dynamic programing type problems when the graphs have cycles.

Is pi a good random number generator?
mmm I wonder if there is a relationship between ease' of spigot algorithm and goodness' of equidistribution?

Is it possible to use linear programming to solve this problem?
Perhaps people on stack overflow would be able to help you out on this one too?

I doubt it. I personally am much happier believing a published proof (that I can't find an error in) than the output of some sort of RNG built by hand in the real world.

but +1 anyway because I think this formula is really cool.

Funky congruences
Perhaps I don't understand your question properly, but this looks like en.wikipedia.org/wiki/Chinese_remainder_theorem

@Sune: Fantastic! Now I can't even trust my own sense of `nice'.

Beginning a sentence with a mathematical symbol
@Vectornaut: Great, now I am totally confused :) I am going to undelete my answer. Gowers had convinced me that it was wrong, but now I really am not sure. If people don't like the answer they should mark it down so that it can at least inform people of what not to do!
