我正在嘗試使用SCIP求解器(http://scip.zib.de/)。我的輸入(1.lp)採用lpsolve格式。它看起來像這樣:SCIP無法讀取我的輸入

max: +2 x_0_0; 
+x_0_0 <= 1; 
+x_0_0 <= 1; 
-3x_0_0 <= 0; 
0 <= x_0_0 <= 1; 
int x_0_0; 

我跑SCIP是這樣的:

"c:\Program Files\SCIP\scip.exe" -f 1.lp -l 1.lp.out 

然而,SCIP生成的輸出:

user parameter file <scip.set> not found - using default parameters 

read problem <[...]1.lp>

    input: 
     ^
error reading file <[...]1.lp> 

我想這意味着它是一個空白窒息。 .. 我究竟做錯了什麼?

編輯:

見我的答案的詳細信息。以CPLEX格式提供輸入後,一切正常。
