B* search algorithm


B* search algorithm

In computer science, B* (pronounced "B star") is a best-first, graph search algorithm that finds the least-cost path from a given initial node to one goal node (out of one or more possible goals). First published by Hans Berliner in 1979, it is related to the A* search algorithm. It stores intervals for nodes of the tree as opposed to single point-valued estimates. Then, leaf nodes of the tree can be searched until one of the top level nodes has an interval which is clearly "best."
