Beam Search is a greedy search algorithm similar to Breadth-First Search (BFS) and Best First Search (BeFS). In fact, we’ll see that the two algorithms are special cases of the beam search. Let’s assume that we have a Graph () that we want to traverse to reach a specific node.

WebAs what we said earlier, the greedy best-first search algorithm tries to explore the node that is closest to the goal. This algorithm evaluates nodes by using the heuristic function h(n), that is, the evaluation function is equal to the heuristic function, f(n) = h(n). This equivalency is what makes the search algorithm ‘greedy.’ Webgreedy best first search
