In the case of transportation problems, the algorithm is essentially a disguised form of the dual simplex algorithm of 4§2.

Assignment problems, which are special cases of transportation problems, pose difficulties for the transportation algorithm and require the development of an algorithm which takes advantage of the simpler nature of these problems.

To handle unacceptable routes in a transportation problem where cost is to be minimized, infeasible arcs must be assigned negative cost values.

A solution to a transportation problem that has less than m n 1 cells with positive allocations in the transportation tableau is a.
