Hi,

I'm not very understand the model status INTERRUPTED. I have many models and some of them will have a status of 11. The documentation tells me that "Optimization was terminated by the user". However, I think I do nothing. Is it caused by callback or timeout?

Thank you!

  Gurobi could terminate with an \(\texttt{INTERRUPTED}\) status if:

  1. The code calls a function that terminates a solve. For example, a Python project might call Model.terminate() (typically done in a callback) or Model.cbStopOneMultiObj() (must be done in a callback).
  2. The Gurobi process receives the interrupt signal (SIGINT). This most commonly occurs when the solve is interrupted manually with Ctrl-C, though the signal could also be sent programmatically.

  In what environment are you using Gurobi? Does your code terminate the solve from a callback function?

  Thank you very much for the answer, I'm using Python. I think I have figured out this question.
