CBCソルバー(デフォルト)並列処理 pythonの線形計画法ソルバーpulpを並列で計算する方法です。 例えば、4スレッドで実行するなら import pulp prob = pulp.LpProblem(sense=pulp.LpMinimize) (省略) prob.solve(pulp.PULP_CBC_CMD(threads=4)) と書きます。 PULP_CBC_CMDには他にもオプションを入れることができます。 PULP_CBC_CMD(path ...

Modeling MILP requires knowledge and ingenuity — We will learn some typical MILP formulations here: 1 Native MILP Formulations “Lumpy” Linear Programs Knapsack Models Assignment and Matching Models Scheduling Models 2 Approximations of Nonlinear Models as MILPs Separable Programming For additional examples, see Rardin (1998), Chapter 11
SCIP (Solving Constraint Integer Programs) is a mixed integer programming solver and a framework for Branch and cut and Branch and price, developed primarily at Zuse Institute Berlin. Unlike most commercial solvers, SCIP gives the user low-level control of and information about the solving process.
In this series of posts, we explore some linear programming examples, starting with some very basic Mathematical theory behind the technique and moving on to some real world examples. We will be using python and the PuLP linear programming package to solve these linear programming problems. PuLP largely uses python syntax and comes packaged ...
Jan 25, 2014 · This tutorial and example problem gives details on exhaustive search and branch and bound techniques for solving Mixed Integer Linear Programming (MILP) problems. Category
Example: Optimal Bond Portfolio A bond portfolio manager has \$100K to allocate to two different bonds. Bond Yield Maturity Rating A 4 3 A (2) B 3 4 Aaa (1) The goal is to maximize total return subject to the following limits. The averageratingmust be at most 1.5 (lower is better). The averagematuritymust be at most 3.6 years.
