This is related to the NP-complete subset sum problem...

See: Subset Sum Problem

This is most likely only relevant if your set is very large. There is an algorithm to solve it in polynomial time that trades off non-polynomial high memory usage for fast processing time.

See: Polynomial Time Dynamic Programming Solution
