Hi,

I'm trying to have a 2D array inside a tuple as below:

tuple m1{

 int index ;

 int m2[1..4][1..5];

} 

It dosent let me to define the m2 inside the tuple. How can I do this ?

Thanks

Mike

Hi,

indeed in documentation

IDE and OPL > Optimization Programming Language (OPL) > Language Reference Manual > OPL, the modeling language > Data types > Data structures

Data types not allowed in tuples

• Sets of tuples (instances of IloTupleSet)

• Arrays of strings, tuples, and tuple sets

• Multidimensional arrays

So as a workaround you could try to turn your 2D array into 1D

Hi,

another workaround is to use a 2D array indexed by the tuple set, so it gets a 3D array:

tuple m1{

 int index ;
 
}

{m1} s={<1>,<2>};

int m2[s][1..4][1..5];

regards
