Webb. Greedy Best First Search Algorithm. The nearest node to the goal node is extended in greedy search methods. A heuristic function h is used to compute the proximity factor (n). The distance between one node and the end or goal node is estimated by h(n). The closer the node is to the endpoint, the smaller the value of h(n). how to survive a boring job https://shoptoyahtx.com
