OnDeltaImprovement¶

class ioh.iohcpp.logger.trigger.OnDeltaImprovement(self, delta: float = 1e-10)¶

Bases: Trigger

Trigger that evaluates to true when improvement of the objective function is observed of at least greater than delta. It keeps the best value of a run, so loggers used at the same time (e.g. in different threads) each need their own, rather than sharing ON_DELTA_IMPROVEMENT.
