CPLEX 数学模型转换为代码

Question

我是 CPLEX 的新手，我正在将数学模型转换为代码。有些输出是错误的，我不知道为什么。我可能会问你的问题是，以下约束是否正确转换为代码。

Constraint

range t=1..2;
range v=1..4;
range vl=0..4;
range vll=1..5;
dvar boolean x[vl][vll][t];
      
forall (i in v, k in t)
 constraint:     
sum(j in vll: j!=i) x[i][j][k] == sum (j in vl: j!=i) x[j][i][k];

Answer 1

range t=1..2;
range v=1..4;
range vl=0..4;
range vll=1..5;
dvar boolean x[vl][vll][t];

subject to
{
      
forall (i in v, k in t)
 constraint1:     
sum(j in vll: j!=i) x[i][j][k] == sum (j in vl: j!=i) x[j][i][k];

}

工作正常
