Cost-adapted task
A cost-adapting transformation of the root task.
adapt_costs(cost_type=normal)
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 algorithms, but is supported for both.
