I am developing a model with proc optmodel and as I go through the process of testing and verifying solution values I am having to go through a very large number of variables, but the solution is sparse with most of them 0. Is there a way to print out the variable without all the 0 values?

 

For example "print DecisionVariable;" yields:

Set1Set2Set3DecisionVariable
1110
1211
1310
2110
2210
2310
3110
3210
3310

 

But I would like something that will just result in:

Set1Set2Set3DecisionVariable
1211

Here's one way, by using a selection expression in the PRINT statement:

 

print {i1 in Set1, i2 in Set2, i3 in Set3: DecisionVariable[i1,i2,i3].sol > 0.5} DecisionVariable;

Thank you so much. I just had to add some contingent clauses based on what my variable had that I hadn't mentioned above after the : (e.g. i1<>i2 etc.) and that worked perfectly.
