Web21/10/04 AIPP Lecture 9: Informed Search Strategies 4 Best-first search • To implement an informed search strategy, we need to slightly modify the skeleton for agenda-based search that we've already seen. • Again, the crucial part of the skeleton is where we update the agenda. • Rather than simply adding the new agenda items to the WebIt can be divided into five main types: Before learning about Artificial Intelligence, you should have a basic understanding of the following to be able to grasp the concepts easily: Breadth-first search Uniform cost search Depth-first search Iterative deepening depth-first search Bidirectional Search Informed Search WebGreedy search For a node n in the search tree, . Let h(n) = an estimate of the cost of the cheapest path from n to a goal state. This is the (heuristic) evaluation function. (Note that h(n) is 0 when n is a goal state.). Greedy search selects the next node to expand based upon the function h.. Greedy search can work quite well, but it does have problems: pinfold darlaston
