at first , thank you everybody here, I learned a lot from this forum.and I keep on growing^.^

I wrote a programe and get the answer Output[P][bminusc]
and  the code like
  range P = 1..3;
              range B =1..7;
              range C = 1..3;
  {int} bminusc = {b-c| b in B,c in C};

dvar int+ Output[P][bminusc];

now I get the  Output  from Output[P][-1], Output[P][0], Output[P][1].....Output[P][7],
if I want to get the Output of range bminusc>=1, it means I only want to get the answer Output[P][1] to Output[P][7],
shall I write a execute to do it?  and how does it like?
waiting for your help

thanks a lot.

What about this :


range P = 1..3;
              range B =1..7;
              range C = 1..3;
 
{int} bminusc = {b-c| b in B,c in C};

dvar int+ Output[P][bminusc];

constraints {
  // your constraints
}

{int} filteredIndexes = {i | i in bminusc : i >= 1};

int filteredResult[p in P][b in filteredIndexes] = Output[p][b];

execute {
  // For debug
  writeln(filteredResult);
}
