Description

template<typename State, typename Action, class Derived>
class probfd::policy_pickers::StablePolicyPicker< State, Action, Derived >

CRTP base class for stable policy picker implementations.

Public Member Functions
int	pick_index (MDP< State, Action > &mdp, std::optional< Action > previous_greedy, const std::vector< Transition< Action > > &greedy_transitions, algorithms::StateProperties &properties) override
	Selects a greedy transition from multiple candidates by returning its index in the candidate list.
virtual void	print_statistics (std::ostream &)
	Prints statistics to an output stream, e.g. the number of queries made to the interface.

pick_index()

template<typename State , typename Action , class Derived >

int probfd::policy_pickers::StablePolicyPicker< State, Action, Derived >::pick_index ( MDP< State, Action > & mdp, std::optional< Action > incumbent_greedy, const std::vector< Transition< Action > > & greedy_transitions, algorithms::StateProperties & properties )

overridevirtual

Selects a greedy transition from multiple candidates by returning its index in the candidate list.

Parameters

mdp	- The MDP in which the search is performed.
incumbent_greedy	- The incumbent greedy action.
greedy_transitions	- A list of candidate greedy transitions.
properties	- The interface to the heuristic search algorithm. Can be used to query additional information about the involved states and actions.

Implements probfd::algorithms::PolicyPicker< State, Action >.
