Best-First Search Details
Note that priority queue is implemented using Min or Max Heap, and insert and remove operations take O log n time. Performance of the algorithm depends on how well the cost or evaluation function is designed. Recommended Posts: Repeatedly search an element by doubling it after every successful search Why is Binary Search preferred over Ternary Search? Improved By : ManuelRaimann.

Apr 27, Actually in such a case no "search" is really needed, since the path from the initial state to the final state is known. Both above cases can be handled well in computer science.
AI is interested in the situation in the middle: the intermediate nodes do have information on how promising each option is, though the information is not always accurate and certain. A " heuristic function " is a function used to rank the alternatives in each step according to available information.
Such a function is usually based on experience and intuition about the given problem.
Heuristic search is similar to depth-first search and breadth-first search, except that its "open-node list" is a priority queue , in which the nodes are sorted by a heuristic function. Consequently in every step the algorithm explores the current-best direction, therefore it is also called "best-first search". The actual efficiency of such an algorithm is determined by the quality of the heuristic function.
