我想了解如何使用NEOS Server for SCIP。我已阅读关于CPLEX LP file format的教程。但是我仍然无法获得任何结果。如何将NEOS服务器用于SCIP?
让我们在教程中提供的示例:
Maximize
obj: x1 + 2 x2 + 3 x3 + x4
Subject To
c1: - x1 + x2 + x3 + 10 x4 <= 20
c2: x1 - 3 x2 + x3 <= 30
c3: x2 - 3.5 x4 = 0
Bounds
0 <= x1 <= 40
2 <= x4 <= 3
General
x4
End
以什么格式(文件扩展名),我有救了吗?我尝试了.MPS
并使用1st按钮上传(输入MPS格式数据文件的完整路径)。但我得到:
error reading file <sample.mps>
SCIP> file <sample.osil> not found
SCIP> limits/time = 36000
SCIP> loaded parameter file <scip.set>
SCIP>
no problem exists
SCIP>
written solution information to file <results1>
SCIP>
written statistics to file <results2>
SCIP> solution status: unknown
no solution available
SCIP Status : initialization
Original Problem : no problem exists.
