Michael . Sedivy. Daniel . Eiland. Introduction. Given a function F(x), how do we determine the location of a local extreme (min or max value)?. Two standard methods exist :. The Transportation and Assignment Problems. Introduction. Transportation problem. Many applications involve deciding how to optimally transport goods (or schedule production). Assignment problem. Deals with assigning people to tasks. Lecture 7. Constantinos Daskalakis. Sperner’s. . Lemma. (.

The process of eliminating artificial variables is performed in phase- I of the solution and phase-II is used to get an optimal solution. Since the solution of LPP is computed in two phases, it is called as Two- Phase Simplex Method..
