Heuristic Search Planners

Heuristic search planners search state space with a heuristic that can be extracted automatically from the problem encoding, and then combined with standard search algorithms. Success is influenced by factors such as the choice of heuristic, search algorithm and search direction. They are arranged here in alphabetical order.
