Unbounded optimal solution
WebSince the feasible region is unbounded there may be no maximum value of z. For x≥4, (x,0) is a feasible solution. At (x,0), z=2x. Therefore as x increases without bound, z increases … WebAn unbounded solution of a linear programming problem is a situation where objective function is infinite. A linear programming problem is said to have unbounded solution if …

WebAx ≤b is has a solution x. Then by weak duality, cTx a lower bound for all solutions to the dual, in contradiction to the fact that the dual is unbounded. •Primal feasible and bounded, dual infeasible is impossible: If the primal has an optimal solution, the duality theorem tells us that the dual has an optimal solution as well. WebHowever, the basic question of whether an optimal solution even exists has not been systematically addressed yet, and it is time to do it now. ...

Web30 Jan 2024 · An unbounded solution of a linear programming problem is a solution whose objective function is infinite. A linear programming problem is said to have unbounded … WebIn 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 …
Webunique optimal solution or could have an infinite number of optimal solutions. Moreover the set of optimal solutions may also be unbounded. This example also illustrates that if an LP (whose feasible region does not contain a line) has an optimal solution then there is an extreme point (recall the definition of extreme points of convex sets ...
