Mixed-Integer Programming (MIP) – A Primer on the Basics

WebWhen there are integer constraints on only some of the variables, the problem is called a mixed-integer program (MIP). Example integer programming problems include portfolio optimization in finance, optimal dispatch of generating units (unit commitment) in energy production, design optimization in engineering, and scheduling and routing in ... WebInteger Linear Programming • Chapter 9 Integer linear programs (ILPs) are linear programs with (some of) the variables being restricted to integer values. For example max 3x1 + 4x2 − 6x3 s.t. x1 + x2 − x4 ≥ 7 x1 + 2x2 + 4x3 = 3 x1,x2,x3 ≥ 0 x1,x2,x3 are integers pure integer linear program min 2x1 + 9x2 − 5x3 s.t. 4x1 + x2 − 6x4 ...

WebThere are two main reasons for using integer variables when modeling problems as a linear program: The integer variables represent quantities that can only be integer. For example, it is not possible to build 3.7 cars. The integer variables represent decisions (e.g. whether to include an edge in a graph) and so should only take on the value 0 or 1. WebInteger programming expresses the optimization of a linear function subject to a set of linear constraints over integer variables. The statements presented in Linear …
