Traveling Salesman Problem (TSP)
The TSP is a classical problem belongs to
the NP-hard class. The TSP defined as a task for
searching the optimal path in a case of a single
vehicle has to visit set of customers (Nodes) exactly
once before return to its starting position (Calvo,
2000). Figure 6 shows an example of TSP through
8 nodes. Figure 6(a) and figure 6(b) show a feasible
path and a better path of the same 8 nodes problem
respectively.
