adapt_costs
adapt_costs(transform=no_transform, cost_type=NORMAL)
transform (AbstractTask): Parent task transformation
cost_type ({NORMAL, ONE, PLUSONE}): Operator cost adjustment type. No matter what this setting is, axioms will always be considered as actions of cost 0 by the heuristics that treat axioms as actions.
NORMAL: all actions are accounted for with their real cost
ONE: all actions are accounted for as unit cost
PLUSONE: all actions are accounted for as their real cost + 1 (except if all actions have original cost 1, in which case cost 1 is used). This is the behaviour known for the heuristics of the LAMA planner. This is intended to be used by the heuristics, not search engines, but is supported for both.
