So … WebThis class of algorithms is also sometimes referred to as informed search strategies. A crucial component to this function f(v) is a heuristic function h(v;d) which provides a lower bound on the cost of the route between some vertex v and the destination d. A well known heuristic function is the Euclidean distance between v and d.
