Hey guys,

I am currently trying to code a model in which I have a range t, going let's say from 0 to 50. 

For one of the constraints though, I need to differ the range of my integer parameter t, so that it does not exceed the total time horizon.

For specifically, I am trying to model a sum which ranges from (t+1 to t+2), but still the last t must not exceed 50, thus in this constraint not exceed 48 (as two are added in my sum).

Does anybody know how to code this?

Best regards

Peter

Hi,

range r=1..50;
 
 int v[i in r]=i;
 
 int result=sum(i in r:((i+2) <=50)) v[i];
 
 execute
 {
 writeln(result);
 }    

regards
