Postage stamp problem + 1, etc.), but to get 13 cents one must use at least four stamps. Mathematically, the problem can be formulated as follows: This problem can be solved by brute force search or backtracking with maximum time proportional to |"V" |, where |"V" | is the number of distinct stamp values allowed. Therefore, if the capacity of the envelope "m" is fixed, it is a polynomial time problem. If the capacity "m" is arbitrary, the problem is known to be NP-hard. Postage stamp problem The postage stamp problem is a mathematical riddle that asks what is the smallest postage value
