What is a basic feasible solution?
- basic feasible solutions (BFS): a basic solution that is feasible. That is Ax = b, x ‚ 0 and x is a basic solution. The feasible corner-point solutions to an LP are basic feasible solutions. The Simplex Method uses the pivot. procedure to move from one BFS to an “adjacent” BFS with an equal or better objective function value.
How do you find the basic feasible solution to P1?
- Then P has at least one basic feasible solution because the feasible region of Pis a polyhedral set and we are assured by Lemma4.41that this set has at least one extreme point.

What are the mbinding constraints of a basic feasible solution?
- At any basic feasible solutions we have chosen mvariables as basic. This basic feasible solution satisfes Bx B= b and thus provides mbinding constraints. The remaining variables are chosen as non-basic and set to zero, thus x N= 0, which provides n mbinding constraints on the non-negativity constraints (i.e., x 0).
