** - Optimization Methods 50:198:461, 56:198:561**

Introduction to various methods based on linear programming (LP) to solve
discrete optimization problems. The topics covered include introduction to
non-linear optimization, and especially linear optimization (linear
programming with the simplex algorithm); network flows, and application
of LP-based techniques to solve certain optimization problem.
Prerequisites: 50:640:121 or 50:640:130; and 50:640:250.
