WebDeﬁnition: A point p of a contex set S is an extreme point if each line segment that lies completely in S and contains p has p as an endpoint. An extreme point is also called a corner point. Fact: Every linear program has an extreme point that is an optimal solution. Corrolary: An algorithm to solve a linear program only needs to consider WebOne obvious solution is to set the objective variables x1 = x2 = 0, which corresponds to the extreme point at the origin. If one of the objective variables is increased from zero while the other one is fixed at zero, the objective value x0 will increase as desired (subject to the slack variables satisfying the equality constraints).
