WebBest-first search is a class of search algorithms, which explores a graph by expanding the most promising node chosen according to a specified rule..

Main idea: select the path whose end is closest to a goal according to the heuristic function. Best-first search selects a path on the frontier with minimal \(h\)-value. It treats the frontier as a priority queue ordered by \(h\). Greedy search example: Romania. This is not the shortest path! Greedy search is not optimal harrison land act https://thencne.org
