WebAccording to the Mixed-Integer Linear Programming Definition , there are matrices A and Aeq and corresponding vectors b and beq that encode a set of linear inequalities and linear equalities. A · x ≤ b A e q · x = b e q. These linear constraints restrict the solution x. Usually, it is possible to reduce the number of variables in the ... WebIt is required to find such an itinerary which minimizes the total distance traveled by the salesman. Note that if t is fixed, then for the problem to have a solution we must have tp ≧ n. For t = 1, p ≧ n, we have the standard traveling salesman problem. Let dij ( i ≠ j = 0, 1, … , n) be the distance covered in traveling from city i to ...
