A handbook for travelling salesmen from 1832 mentions the problem and includes example tours through Germany and Switzerland, but contains no mathematical treatment. [2] William Rowan HamiltonWhat we know about the problem: NP-Completeness. ε. In vector/matrix notation: An integer program (IP) is an LP problem with one additional constraint: all are required to be integer: x s.t. Ax ≤ b x ≥ 0 x ε. We'll assume the TSP is a Euclidean TSP (the formulation for a graph-TSP is similar). The traveling salesman can arise in various contexts. It can be applied in the field of computer wiring, vehicle routing, and even in job shop scheduling. An excellent example of TSP is when a given set of cities and distances between different pairs of cities, one will try to find the shortest way possible (Boese, 1995).
