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.’
