Hi,everyone,

I need to access the interval solution value with opl interface in .net, here is my invoke method. line 1 - 5 work well, but line 6 raise a AccessDenied exception. anybody can help?

Thanks.

subCP.Next();
1 : ITupleSet alternatives = subOpl.GetElement("Alternatives").AsTupleSet();
2 : IIntervalVarMap altIntervals = subOpl.GetElement("AltIntervals").AsIntervalVarMap();
3 : foreach (ITuple tuple in alternatives)
4 : {
5 : IIntervalVar intervalVar = altIntervals.Get(tuple);
6 : subCP.GetStartMin(intervalVar);
7 : }

Hi,

You should retrieve the interval solution value as a tuple (and as a tupleMap for interval array).
In your case, you could do:

ITupleSet alternatives = opl.GetElement(
"Alternatives").AsTupleSet(); ITupleMap altIntervals = opl.GetElement(
"AltIntervals").AsTupleMap(); IMapIndexArray index = oplF.MapIndexArray(0); ITuple result = altIntervals.MakeTuple();   foreach (ITuple t in alternatives) 
{ index.Add(t); altIntervals.GetAt(index, result); Console.Out.WriteLine(
"present: " + result.GetIntValue(
"present") + 
" start: " + result.GetIntValue(
"start") + 
" end: " + result.GetIntValue(
"end") + 
" size: " + result.GetIntValue(
"size")); index.Clear(); 
}

Hope this help.

Yes， It works for solution value of interval, can i get the startmin and endmax values after propagation ?

thanks.
