What is a basic feasible solution to an LPP?

A basic feasible solution is a solution which satisfies all the constraints and also the non negativity restrictions. How can you show that the convex combination of feasible solutions to an LPP is again feasible solution to the LPP? This is because the feasible region of LPP is convex.

Explanation: The multiple optimal solutions arise in a linear programming problem with more than one set of basic solutions that can minimize or maximize the required objective function. The multiple optimal solutions are called the alternate basic solution. What is optimal solution of LPP?

How many LP problems are possible?

4 of them are feasible. However, in a lot of real-world LP problems the numberof variables and the number of constraints are much higher. For example, if aproblem has n= 30 decision variables andm= 35 problem constraints, thenumber of possible basic solution becomes approximately31018.

What is an optimal solution to an LP?

An optimal solution to an LP is a feasible solution such that there does not exist any other feasible solution yielding a better (smaller or larger in the case of minimization and maximization, respectively) objective function value. An LP may have zero, one, or an infinite number of optimal solutions.
