    Hi Peng Lin,

    You are using the methods correctly, so the most probable explanation is an issue with the solution.
    Maybe it is rejected because it is "slightly" infeasible due to some numerical issues?
    Is the objective function in this model and your heuristics exactly the same? If not, the solution value for this model's objective function might be higher than the current incumbent and is therefore rejected?
    It is hard to debug this issue on our side.

    Best regards,
