Get UNEXPLORED status after sometime, #525

Closed omidziaee closed 1 year ago

omidziaee commented 1 year ago

I am running almost the same problem each 5 minutes, just some inputs to the problem changes. At first it runs smoothly and after a while it times out (I set the abort time to 100 seconds) and get the UNEXPLORED status. Is there a flag or something that I need to set at the end of each round to fully restart the solver? Any help would be appriciated. Omid

You have to give more details on how you do things. Are you using ExpressionsBasedModel? Which solver is used?

omidziaee commented 1 year ago

Yes I am using ExpressionsBasedModel and the default solver.

omidziaee commented 1 year ago

How do you set the solver? I assume ExpressionBasedModel selects the solver based on the problem. Am I wrong?

apete commented 1 year ago

Yes, ExpressionBasedModel selects an appropriate solver based on the problem type. There's a method addIntegration(Integration<?>) that allows you to add 3:d party solvers.
