Search Algorithm - Which are the best first search algorithm?


Many people consider the A* Search Algorithm to be the best option for first search. It makes use of a heuristic function h(n) and a cost function g(n) that calculates an approximation of the cost to travel from the origin to node n. This algorithm is a powerful tool for addressing problems because it combines the greatest features of greedy best-first search and Uniform Cost Search (UCS).
