class MostPromisingTrajectoryTracker[source]#

Bases: object

This is a tracker for tracking the most promising next action, used in joint learning settings where we don’t have knowledge about the actual transition function or the goal.

Methods

`check`(new_score)	If the new score is better than the current best score, return True.
`update`(new_score, solution)	Update the best score and the solution.

Attributes

`threshold`	A score threshold.
`best_score`	The best score achived so far.
`solution`	The solution associated with the best_score.

__init__(threshold)[source]#

Initialize the tracker.

Parameters:: threshold (float) – the threshold for the score.

__new__(**kwargs)#

check(new_score)[source]#

Return type:: bool

update(new_score, solution)[source]#

Update the best score and the solution.

Parameters:

new_score (float) – the new score.
solution (Any) – the new solution.

best_score: float#: The best score achived so far.
