Question: Given an integer m n matrix A and an integer m-vector b, the 0-1 integer-programming problem asks whether there exists an integer n-vector x

Given an integer m × n matrix A and an integer m-vector b, the 0-1 integer-programming problem asks whether there exists an integer n-vector x with elements in the set {0, 1} such that Ax ≤ b. Prove that 0-1 integer programming is NP-complete.
