The document discusses linear programming, which is a technique for solving optimization problems with linear objective functions and constraints. It provides the standard form of a linear programming problem involving decision variables, an objective function to maximize, and constraints. Examples of both a graphical and algebraic (simplex method) solution are presented. The key concepts of feasible region, optimal solution, entering and leaving variables in the simplex method are explained. Duality, where every linear programming problem has an associated dual problem, is also introduced.
