这一范式被称为嵌入机器学习模型的不确定参数优化问题,如下图所示 在上图中本质上是一个 两阶段法,在第一个阶段(Prediction Model)我们是采用机器学习算法对不确定参数 c 进行拟合,在第二阶段(Optimization Model)我们是采用机器学习模型预测的结果输入到我们的优化模型中,此时我们的优化模型就变成了确定性的优化问题...
Gurobi can either presolve a model or start from an advanced basis or primal/dual solution pair. Often the solve from scratch of a presolved model outperforms a solve from an unpresolved model started from an advanced basis/solution. It is impossible to determine a priori if presolve or st...
To check the state of the asynchronous optimization, query the Status attribute for the model. A value of IN_PROGRESS indicates that the optimization has not yet completed. When you are done with your foreground tasks, you must call sync to sync your foreground program with the asynchronous ...
市场上最受欢迎的商业求解器之一是Gurobi(Gurobi), 以共同创始人顾宗浩, 爱德华·罗斯伯格和罗伯特·比克斯比(Robert Bixby)的名字命名, 他们都是商业求解器领域的先驱。 Gurobi在最近的历史中为许多著名的优化项目提供了动力, 包括FCC的带宽分配项目和Pennsylvania State Prison的囚犯重新分配项目。

The Gurobi interface for MATLAB®allows users to build an optimization model, pass the model to Gurobi, and obtain the optimization result, all from within the MATLAB environment. It can be used to solve optimization problems using any of the following forms: linear constraints, bound constraints...
the problem itself is quite massive in it's full size so I wanted to explore something like multiple column insertion within each iteration. You'll also notice that I delete the model within each iteration due to the sheer size of even the reduced model. It actually runs much faster when ...
