For various stopping criteria, a warning is raised upon hitting (https://github.com/fides-dev/fides/blob/master/fides/minimize.py#L530). This leads to quite verbose outputs when using fides in a multi-start setting or e.g. for profile calculation. I'd argue that stopping is quite a natural occurrence in an optimization, therefore not requiring the raising of a warning, but rather on the level of info, reducing the verbosity.
