Unbounded solution Simplex example - Linear programming

Webbunbounded solution, then the dual (primal) problem is infeasible. ... • At each iteration of the dual simplex method, we require that: and since these variables are a dual feasible solution. ... optimal final tableau for this example is given by setting θ equal to zero. WebbThese solutions are feasible as longer as \(t \ge 0\) and we have \(\lim_{t \to \infty} z = \infty\). Whenever a lineal item is unbounded the Simplex Method will eventually tell us (by attaining a glossary that has an entering variable but no exiting variable) and are pot produce an unbounded one-parameter family of feasible solutions as above. WebbAs a simple example, you could add a new "slack" variable on each capacity constraint, having a very high penalty cost. Then infeasibilities in your capacities would be signalled by positive values for these slacks at the optimal solution, rather than by a mysterious lack of feasibility in the linear program as a whole. high print volume
