Terminate on lack of progress / stagnation

[Plug11]

I was wondering whether anyone has considered adding a new termination criteria if the solver has not made a significant improvement in the objective in given number of iterations?

Maybe there would be two config options controlling this:

• max_no_progress_iterations - the maximum number of consecutive iterations that no progress is made
• no_progress_rel_tolerance - the relative tolerance in objective which must be exceeded to make progress
