The Subset Sum Problem is a member of the NP-complete class, so no known polynomial time algorithm exists for it. Although there are polynomial time approximations and heuristics, these are not always acceptable, yet exact-solution algorithms are unfeasible for large input. Quantum computation ...
假设有一个计算 Subset Sum 的算法，ai' := ai * 2^(logn) +1，k' := k * 2^(logn) +M。

The given sum problem is NP-complete. For small cases, it be solved using generating functions. Consider the number of ways to select out of given integers such that their sum equals , and define the generating function (9) Upon expanding in powers of , this becomes (10) But as ...
For example, given the set {−7, −3, −2, 5, 8}, the answer isyesbecause the subset {−3, −2, 5} sums to zero. The problem isNP-complete. An equivalent problem is this: given a set of integers and an integers, does any non-empty subset sum tos? Subset sum can al...
