Graphically, that means the line furthest to the upper right that still touches the feasible region on at least one point. To illustrate, Real world uses for linear functions include solving problems and finding unknowns in engineering, economics and finances. com/file/d/1yYwsI7nVOYiiQPjQMTEcTvrM 1. 63–94. For a problem to be a linear programming problem, the decision variables, objective function and constraints all have to be linear functions. The feasible region of the linear programming problem is empty; that is, there are no values for x 1 and x 2 that can simultaneously satisfy all the constraints. Linear programming problems are almost always word problems. It is also represented by Lpp. Lecture 15: Linear Programming. again the linear program (1). Objective function, 3.
