readth First Search (BFS) searches breadth-wise in the problem space. Breadth-First search is like traversing a tree where each node is a state which may a be a potential candidate for solution. Breadth first search expands nodes from the root of the tree and then generates one level of the tree at a time until a solution is found. It is very easily implemented by maintaining a queue of nodes. Initially the queue contains just the root. In each iteration‚ node at the head of the queue is removed

h(n)=0 NEVER over-estimates the remaining optimal distance to a goal node. 3- A* is of no use in robotics because percepts‚ states‚ and actions are continuous FALSE‚ the continuous spaces can be discretized. A* (or variants) are widely used 4- Breadth-first search is complete even if zero step costs are allowed. TRUE Because if there exists a goal it occurs at finite depth d and will be found in O(bd) steps. “Complete” means “will find a goal when one exists” --- and does NOT imply “optimal‚”

Action-Based Discretization for AI Search Dr. Todd W. Neller* Department of Computer Science Gettysburg College Campus Box 402 Gettysburg‚ PA 17325-1486 Introduction As computer gaming reaches ever-greater heights in realism‚ we can expect the complexity of simulated dynamics to reach further as well. To populate such gaming environments with agents that behave intelligently‚ there must be some means of reasoning about the consequences of agent actions. Such ability to seek out the ramifications

CS306- INTELLIGENT SYSTEMS Part – A 1. There are well-known classes of problems that are intractably difficult for computers‚ and other classes that are provably undecidable. Does this mean AI is impossible? (2) No‚ it means that AI systems should avoid trying to solve intractable problems. Usually this means they can only approximate optimal behavior. Notice that even humans do not solve NP- complete problems. Sometimes they are good at solving specific instances with a lot of structure

Abstract The large size and the dynamic nature of the Web highlight the need for continuous support and updating of Web-based information retrieval systems. Crawlers facilitate the process by following the hyperlinks in Web pages to automatically download a partial snapshot of the Web. Traversing the web graph in breadth-first search order is a good crawling. This system is

any primary tooth in a child 71 months of age or younger” [2]. Clinical examination of this condition discloses a distinctive pattern‚ and the teeth most often involved are the maxillary central incisors‚ lateral incisors‚ and the maxillary and mandibular 1st primary molars. The maxillary primary incisors are the most severely affected with deep carious lesions usually involving the pulp. In extreme cases‚ early childhood caries can even lead to total loss of the crown structure. Until very recently
