線性規劃與整數規劃模式LinearandInteger ProgrammingModels 1 2.1線性規劃簡介IntroductiontoLinearProgramming •線性規劃模型(LinearProgrammingmodel)是在一組「線性」的限制式(asetoflinearconstraints)之下，尋找極大化(maximize)或極小化(minimize)一個特定的目標函數(objectivefunction)•線性規劃模型由下列三個部分...
The chapter focuses on several modeling tricks that enable generation of linear models in the presence of special types of non-linear expressions or in the presence of logic conditions between real/integer variables and/or between binary variables. Typically, a MILP model is considered "good" if ...

The different types of relaxations that can be applied to an MILP problem are: • Linear relaxation: This consists of removing the integrality constraint of a given decision variable. The resulting relaxation is a linear program. This relaxation technique transforms an NP-hardoptimization problem(i...
