Mixed integer linear programming (MILP) is the state-of-the-art mathematical framework for optimization of energy systems. The capability of solving rather large problems that include time and space discretization is particularly relevant for planning the transition to a system where non-dispatchable energy sources are key. Mixed Integer Programming (MIP) has been widely applied to scheduling problems and it is often the initial approach to attack a new scheduling problem. For example, of the 40 research papers published in the Journal of Scheduling in 2014, 14 use MIP, more than any other technology.Constraint programming (CP) has been recently in the spotlight after new CP-based procedures have been incorporated into state-of-the-art solvers, most notably the CP Optimizer from IBM.

May 1, 2021 · Summary. This chapter provides an overview of mixed-integer programming (MIP) modeling and solution methods.In Section 2.1, we present some preliminary concepts on optimization and mixed-integer programming. In Section 2.2, we discuss how binary variables can be used to model features commonly found in optimization problems. Mixed Integer programs (MIPs) are typically solved by the Branch-and-Bound algorithm. Recently, Learning to imitate fast approximations of the expert strong branching heuristic has gained attention due to its success in reducing the running time for solving MIPs. However, existing learning-to-branch methods assume that the entire …In an integer (linear) program, the x_j must take integer values. In a mixed integer (linear) program, only some of the x_j must take integer values. Surprisingly many optimization problems can be naturally modeled as linear or integer programs, and for this reason these techniques are increasingly used across many areas of computer science.(ODT) using mixed-integer programs (MIP), due to algorithmic advances in integer programming and a growing interest in addressing the inherent suboptimality of heuristic approaches such as CART.
