windows+VS2019+gurobi解決方案配置

本文轉載自查看原文 2021-02-28 14:48 279

第一步，VS創建新的解決方案和空項目

一個解決方案下面可以包含多個項目。

右鍵點擊項目名，選擇屬性，進行配置

C:\gurobi911\win64\include

C:\gurobi911\win64\lib

添加附加依賴項

gurobi91.lib;gurobi_c++mdd2019.lib;

如果有需要別的文件，如依靠外部lp文件，添加命令參數

還有一點基本的，把平台Debug設置為x64

OK，現在就可以測試一下了

/* This example creates a very simple Special Ordered Set (SOS) model.
   The model consists of 3 continuous variables, no linear constraints,
   and a pair of SOS constraints of type 1. */

        GRBModel model = GRBModel(*env);

        // Create variables

        // Optimize model

        model.optimize();

    delete[] x;
    delete env;
