ribs.emitters.rankers¶
Rankers for use across emitters.
The rankers implemented in this file are intended to be used with emitters. Specifically, a ranker object should be initialized or passed in the emitters. The Ranker
object will define the rank()
method which returns the result of a descending argsort of the solutions. It will also define a reset()
method which resets the internal state of the object.
When specifying which ranker to use for each emitter, one could either pass in the full name of a ranker, e.g. “ImprovementRanker”, or the abbreviated name of a ranker, e.g. “imp”. The supported abbreviations are:
imp
:ImprovementRanker
obj
:ObjectiveRanker
2obj
:TwoStageObjectiveRanker
