Visual c++ 为什么我的lp文件为每个变量提供了#编号？ 我用ILOG CPLEX用Visual C++ 2015解决了我的问题。通常，当我导出问题的lp文件时，lp文件将不包含变量的任何#编号（例如#0、#1等）。是这样的: \ENCODING=ISO-8859-1 \Problem name: IloCplex Minimize obj: Ope(1,1,1) + Ope(1,1,2) + Ope(1,1,3) + Ope(1,1,4) + Ope(1,1,5) + Ope(1,1,6) + Ope(1,1,7) + Ope(1,1,8) + Ope(1,1,9) + Ope(1,1,10) + Ope(1,1,11) + Ope(1,1,12) + Ope(1,1,13) + Ope(1,1,14) + Ope(1,1,15) + Ope(1,1,16) + Ope(1,1,17) + Ope(1,1,18) + Ope(1,1,19) + Ope(1,1,20) + Ope(1,1,21) + Ope(1,1,22) + Ope(1,1,23) + Ope(1,1,24) + Ope(1,2,1) + Ope(1,2,2) + Ope(1,2,3) + Ope(1,2,4) + Ope(1,2,5) + Ope(1,2,6) + Ope(1,2,7) + Ope(1,2,8) + Ope(1,2,9) + Ope(1,2,10) + Ope(1,2,11) + Ope(1,2,12) + Ope(1,2,13) + Ope(1,2,14) + Ope(1,2,15) + Ope(1,2,16) + Ope(1,2,17) + Ope(1,2,18) + Ope(1,2,19) + Ope(1,2,20) + Ope(1,2,21) + Ope(1,2,22) + Ope(1,2,23) + Ope(1,2,24) + Ope(2,1,1) + Ope(2,1,2) + Ope(2,1,3) + Ope(2,1,4) + Ope(2,1,5) + Ope(2,1,6) + Ope(2,1,7) + Ope(2,1,8) + Ope(2,1,9) + Ope(2,1,10) + Ope(2,1,11) + Ope(2,1,12) + Ope(2,1,13) + Ope(2,1,14) + Ope(2,1,15) + Ope(2,1,16) + Ope(2,1,17) + Ope(2,1,18) + Ope(2,1,19) + Ope(2,1,20) + Ope(2,1,21) + Ope(2,1,22) + Ope(2,1,23) + Ope(2,1,24) + Ope(2,2,1) + Ope(2,2,2) + Ope(2,2,3) + Ope(2,2,4) + Ope(2,2,5) + Ope(2,2,6) + Ope(2,2,7) + Ope(2,2,8) + Ope(2,2,9) + Ope(2,2,10) + Ope(2,2,11) + Ope(2,2,12) + Ope(2,2,13) + Ope(2,2,14) + Ope(2,2,15) + Ope(2,2,16) + Ope(2,2,17) + Ope(2,2,18) + Ope(2,2,19) + Ope(2,2,20) + Ope(2,2,21) + Ope(2,2,22) + Ope(2,2,23) + Ope(2,2,24) \ENCODING=ISO-8859-1 \Problem name: IloCplex Minimize obj: Ope(1,1,1)#0 + Ope(1,1,2)#1 + Ope(1,1,3)#2 + Ope(1,1,4)#3 + Ope(1,1,5)#4 + Ope(1,1,6)#5 + Ope(1,1,7)#6 + Ope(1,1,8)#7 + Ope(1,1,9)#8 + Ope(1,1,10)#9 + Ope(1,1,11)#10 + Ope(1,1,12)#11 + Ope(1,1,13)#12 + Ope(1,1,14)#13 + Ope(1,1,15)#14 + Ope(1,1,16)#15 + Ope(1,1,17)#16 + Ope(1,1,18)#17 + Ope(1,1,19)#18 + Ope(1,1,20)#19 + Ope(1,1,21)#20 + Ope(1,1,22)#21 + Ope(1,1,23)#22 + Ope(1,1,24)#23 + Ope(1,2,1)#24 + Ope(1,2,2)#25 + Ope(1,2,3)#26 + Ope(1,2,4)#27 + Ope(1,2,5)#28 + Ope(1,2,6)#29 + Ope(1,2,7)#30 + Ope(1,2,8)#31 + Ope(1,2,9)#32 + Ope(1,2,10)#33 + Ope(1,2,11)#34 + Ope(1,2,12)#35 + Ope(1,2,13)#36 + Ope(1,2,14)#37 + Ope(1,2,15)#38 + Ope(1,2,16)#39 + Ope(1,2,17)#40 + Ope(1,2,18)#41 + Ope(1,2,19)#42 + Ope(1,2,20)#43 + Ope(1,2,21)#44 + Ope(1,2,22)#45 + Ope(1,2,23)#46 + Ope(1,2,24)#47 + Ope(2,1,1)#48 + Ope(2,1,2)#49 + Ope(2,1,3)#50 + Ope(2,1,4)#51 + Ope(2,1,5)#52 + Ope(2,1,6)#53 + Ope(2,1,7)#54 + Ope(2,1,8)#55 + Ope(2,1,9)#56 + Ope(2,1,10)#57 + Ope(2,1,11)#58 + Ope(2,1,12)#59 + Ope(2,1,13)#60 + Ope(2,1,14)#61 + Ope(2,1,15)#62 + Ope(2,1,16)#63 + Ope(2,1,17)#64 + Ope(2,1,18)#65 + Ope(2,1,19)#66 + Ope(2,1,20)#67 + Ope(2,1,21)#68 + Ope(2,1,22)#69 + Ope(2,1,23)#70 + Ope(2,1,24)#71 + Ope(2,2,1)#72 + Ope(2,2,2)#73 + Ope(2,2,3)#74 + Ope(2,2,4)#75 + Ope(2,2,5)#76 + Ope(2,2,6)#77 + Ope(2,2,7)#78 + Ope(2,2,8)#79 + Ope(2,2,9)#80 + Ope(2,2,10)#81 + Ope(2,2,11)#82 + Ope(2,2,12)#83 + Ope(2,2,13)#84 + Ope(2,2,14)#85 + Ope(2,2,15)#86 + Ope(2,2,16)#87 + Ope(2,2,17)#88 + Ope(2,2,18)#89 + Ope(2,2,19)#90 + Ope(2,2,20)#91 + Ope(2,2,21)#92 + Ope(2,2,22)#93 + Ope(2,2,23)#94 + Ope(2,2,24)#95

我不希望#number出现在我的lp文件中。我该怎么办

LP文件格式不允许变量和/或约束的任意名称。有关详细信息，请访问用户手册

如果任何变量或约束的名称在LP文件格式中不受支持，则必须更改该名称。为避免新名称与任何现有名称发生冲突，CPLEX会将

#number

附加到模型中的所有名称

一个可能/经常不受支持的名称是以

e

开头的名称。如果要导出到LP，请尽量避免使用此类名称
