PPT分享 | 商业求解器ILOG OPL的介绍和使用方法

投稿期刊返修时，审稿人有一条意见是要求我对比自己提出的改进优化算法和商业求解器之间的求解效率的差异，所以我不得不继续学习商业求解器的相关内容，发现还是有一些可以说道的东西。更出名的一个东西是CPLEX，实际上，ILOG OPL（Optimization Programming Language）和CPLEX是IBM决策优化工具链中的核心组件，二者构成建模与求解的协同体系。ILOG OPL负责 建模语言与环境，用声明式语法描述优化问题（如数学规划、约束规划），CPLEX是求解引擎，负责执行计算，寻找模型的最优解（支持线性/整数/二次规划等）。
