range preserving the optimality of the current optimal base, is impractical for the assignment problem. An optimal basic … solution of the assignment problem is inherently degenerate, so it may be that the optimal base has changed but the optimal … assignment remains unchanged. Furthermore, elements of a column (or row) in a cost matrix of assignment problem are usually …
