What is a feasible solution in LPP?
- A feasible solution is a set of values for the decision variables that satisfies all of the constraints in an optimization problem. The set of all feasible solutions defines the feasible region of the problem. Thereof, what is basic feasible solution in LPP?
Is an LP infeasible?
- It does not violate even a single constraint. Any x = (x 1, x n) that satisfies all the constraints. Alternatively, an LP is infeasible if there exist no solution that satisfies all of the constraints. Hence, if no feasible solution can be constructed, then the LP is infeasible.
What is a feasible solution to a linear programming problem?
- A feasible solution to the linear programming problem should satisfy the constraints and non-negativity restrictions. A feasible solution to an LPP with a maximization problem becomes an optimal solution when the objective function value is the largest (maximum).
What happens if the feasible region of a LPP is unbounded?
- If the feasible region for a LPP is unbounded, maximum or minimum of the objective function Z = ax + by may or may not exist. 43. Maximum value of the objective function Z = ax +by in a LPP always occurs at only one corner point of the feasible region.
