• What is an example of an unbounded solution in linear programming?

  The unbounded solution is explained in the following Example. Consider the following linear programming problem. Maximize 5x1 + 4x2 Subject to: x1 – x2 ? 8 x1 ? 7 x1, x2 ? 0. Note that z2 - c2 < 0 which indicates x2 should be introduced as a basic variable in the next iteration.

• What is unbounded solution in linear programming?

  An 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 its solution can be made infinitely large without violating any of its constraints in the problem.
• When the feasible set is empty, the LP is called infeasible. The maximum value of the objective c?x over feasible x is the optimal value of the LP. If this maximum is infinity, i.e. for any t ? R there exists a feasible x s.t. c?x ? t, then the LP is called unbounded.
