Assume I ahev a tuple like this
and a constraint label d[Maket] associated with Market. Initially, the tuple Market is empty.
I add a new element (a,b) to the tuple Market by Market.add(a,b) and the new elements is added correctly.
Neverthless, when processing d[Market] in the OPL script, an error message arose "index out of bound for array d"
Is there any mean to fix this problem?
