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).
