WebbPros of simplex: Given n decision variables, usually converges in O ( n) operations with O ( n) pivots. Takes advantage of geometry of problem: visits vertices of feasible set and checks each visited vertex for optimality. (In primal simplex, the reduced cost can be used for this check.) Good for small problems. Cons of simplex:
