我在ampl中有一个2维变量,我想显示它。我想更改索引的顺序,但是我不知道该怎么做!我放置了代码,数据和输出,描述了我想要的输出。 这是我的代码:
param n;
param t;
param w;
param p;
set Var, default{1..n};
set Ind, default{1..t};
set mode, default{1..w};
var E{mode, Ind};
var B{mode,Var};
var C{mode,Ind};
param X{mode,Var,Ind};
var H{Ind};
minimize obj: sum{m in mode,i in Ind}E[m,i];
s.t. a1{m in mode, i in Ind}: sum{j in Var} X[m,j,i]*B[m,j] -C[m,i] <=E[m,i];
solve;
display C;
data;
param w:=4;
param n:=9;
param t:=2;
param X:=
[*,*,1]: 1 2 3 4 5 6 7 8 9 :=
1 69 59 100 70 35 1 1 0 0
2 34 31 372 71 35 1 0 1 0
3 35 25 417 70 35 1 0 0 1
4 0 10 180 30 35 1 0 0 0
[*,*,2]: 1 2 3 4 5 6 7 8 9 :=
1 64 58 68 68 30 2 1 0 0
2 44 31 354 84 30 2 0 1 0
3 53 25 399 85 30 2 0 0 1
4 0 11 255 50 30 2 0 0 0
使用glpksol的这段代码的输出就像tis:
C[1,1].val = -1.11111111111111
C[1,2].val = -1.11111111111111
C[2,1].val = -0.858585858585859
C[2,2].val = -1.11111111111111
C[3,1].val = -0.915032679738562
C[3,2].val = -1.11111111111111
C[4,1].val = 0.141414141414141
C[4,2].val = 0.2003367003367
但是我希望结果是这样的:
C[1,1].val = -1.11111111111111
C[2,1].val = -0.858585858585859
C[3,1].val = -0.915032679738562
C[4,1].val = 0.141414141414141
C[1,2].val = -1.11111111111111
C[2,2].val = -1.11111111111111
C[3,2].val = -1.11111111111111
C[4,2].val = 0.2003367003367
有什么主意吗?
答案 0 :(得分:0)
您可以在for
文件中使用printf
循环和.run
命令:
for {i in Ind}
for {m in mode}
printf "C[%d,%d] = %.4f\n", m, i, C[m,i];
甚至:
printf {i in Ind, m in mode} "C[%d,%d] = %.4f\n", m, i, C[m,i];
我没有得到与您相同的数值结果,但是无论如何输出都可以:
C[1,1] = 0.0000
C[2,1] = 0.0000
C[3,1] = 0.0000
C[4,1] = 0.0000
C[1,2] = 0.0000
C[2,2] = 0.0000
C[3,2] = 0.0000
C[4,2] = 0.0000
