WebbObtain an initial basic feasible solution to the following transportation problem using least cost method. Here O i and D j denote i th origin and j th destination respectively. Solution: Total Supply = Total Demand = 24. ∴ The given problem is a balanced transportation problem. Hence there exists a feasible solution to the given problem. WebbAn initial feasible solution, x 0, is randomly generated. Then, in each iteration i, a new solution (y) is randomly generated from the neighborhood, N (x i), of the solution considered in that iteration, x i. If the new solution is better than the current one, then the algorithm moves to that solution.
In the theory of linear programming, a basic feasible solution (BFS) is a solution with a minimal set of non-zero variables. Geometrically, each BFS corresponds to a corner of the polyhedron of feasible solutions. If there exists an optimal solution, then there exists an optimal BFS. Hence, to find an optimal solution, it is … Visa mer Preliminaries: equational form with linearly-independent rows For the definitions below, we first present the linear program in the so-called equational form: maximize Visa mer The set of all feasible solutions is an intersection of hyperspaces. Therefore, it is a convex polyhedron. If it is bounded, then it is a Visa mer As mentioned above, every basis B defines a unique basic feasible solution $${\displaystyle \mathbf {x_{B}} ={A_{B}}^{-1}\cdot b}$$ . In a similar way, each basis defines a solution to the dual linear program: minimize Visa mer • How to move from an optimal feasible solution to an optimal basic feasible solution.
