Summary

Best-first search is a class of search algorithms that expand the "most promising" node in each iteration, using heuristics to determine the order of node expansion. The most important best-first search algorithms include greedy best-first search, A, and weighted A. Best-first search can be implemented as graph search or tree search, with the graph search version being more common. The algorithm uses a MinHeap ordered by an evaluation function f, which can be a combination of path cost and heuristic. Reopening is used to expand duplicate nodes when cheaper paths to their states are found, and it replaces the closed set with a distances hash table to control reopening. The properties of best-first search include completeness if the heuristic is safe, and optimality depends on the evaluation function f.
