Hi,
Is it possible for a callback procedure to save the newest incumbent solution to a case file.
Is an example available?
Edit:
I already installed a callback procedure (SetCallbackNewIncumbent).
How can I access the new incumbent solution from that procedure?
And do I need to send the new incumbent solution to the model first, after which I can send it to a case file, or can I send it to a case file directly?
Thanks!
Best, WM

callback procedure that saves new incumbent solution to case file

In the callback procedure, you can first use function RetrieveCurrentVariableValues to retrieve the variables value from the model;
Then use the .Incumbent suffix to retrieve the new incumbent value
Then use function like CaseFileSave to save those values you need.
code:
RetrieveCurrentVariableValues(AllVariables);
Then use the .Incumbent suffix to retrieve the new incumbent value
code:
MyVariable.Incumbent;
Then use function like CaseFileSave to save those values you need.

Hi,
Thanks for your answer, however I get this error...
The function RetrieveCurrentVariableValues cannot be called from a callback issued by GMP::SolverSessionExecute or GMP::SolverSession::AsynchronousExecute.
Any alternatives?
Thanks, W.

+3Hi Wiet, in this case, you may need to use function GMP::Solution::RetrieveFromSolverSession
