Postage stamp design Postage stamp design Postage stamp design is the activity of graphic design as applied to postage stamps. Many thousands of designs have been created since a profile bust of Queen Victoria was adopted for the Penny Black in 1840; some designs have been considered very successful, others less so. A stamp design includes several elements required for it to accomplish its purpose satisfactorily. Most important is the denomination indicating its monetary value, while international agreements require a country name on almost all types of stamps. A graphic design is very nearly universal; in addition to making counterfeits harder to produce
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
