(这点,未见有博客明确指出,较为隐晦,我已经一一验证以上四点,发现就是gurobi+的原因,与其他三项无关,可能更底层的原因是需要求助yalmip中的部分库函数) 2 导出互相冲突的约束的序号 iis = gurobi_iis(model); 如果程序不报错,那么就别放这行代码进去;如果程序报错,那么这行代码通常需要单独选中后才会运行。 之后...
iis = gurobi_iis(model); %查看约束冲突的序号 gurobi_write(model, 'TestModel.lp');%根据约束冲突的序号找变量名,进而从m文件中找出约束 进阶: sum(iis.Arows) %统计约束冲突的个数 find(iis.Arows==1)-1 %在命令行窗口展现冲突约束的序号,这样就可以不用去在“excel”与“编辑器的Testmodel.lp”间...
You can also let Gurobi compute an IIS, cf. How do I determine why my model is infeasible?. For this you would have to use the gurobi_iss() function and write the resullt to a file via the gurobi_write() function. Best regards, Jaromił 0 Please...
TOMLAB /GUROBI Based on Gurobi 5.6.3 (except Linux 32-bit, which is 5.0.2). TOMLAB /CGO Complete revision. Nine different ways of function transformation now possible. All solvers now prepared for use with multithreading and parfor usage. Optionally, all solvers will try to find all local...
iis = gurobi_iis(model); 如果程序不报错,那么就别放这行代码进去;如果程序报错,那么这行代码通常需要单独选中后才会运行。 之后在工作区会出现iis结构体,其中的iis.Arows的1代表约束冲突,约束序号为该1所在行号。这里参见博客,最好将该列放在excel中行号与1进行对应。可以替换FALSE为空格(如下图)便于后面查找变...
