@martinjrobins @chonlei @mirams can you have a look and see if this makes sense, before I add tests? |

| ### Added | |||
| - [#1508](https://github.com/pints-team/pints/pull/1508) Added a method `OptimisationController.set_max_unmoved_iterations` that allows methods to stop after 1 or more iterations with no significant movement in parameter space. | |||

"unmoved/unchanged" is a bit vague and not immediately obvious to me in terms of whether it refers to xtol or ftol? unmoved parameters, unchanged objective?

I agree! But can't think of anything better that doesn't involve deprecating set_max_unchanged_iterations which is probably one of the most used methods of the controller class

Hmmmm, given all the different names that exist already, inventing another set that are pints specific doesn't seem great anyway - and even more so if they are vague!
