This new edition provides a comprehensive, colorful, up-to-date, and accessible presentation of AI without sacrificing theoretical foundations. . Uninformed search strategies: AKA "Blind search" Uses only information available in problem definition Informally: Uninformed search: All non-goal nodes in frontier look equally good Informed search: Some non-goal nodes can be ranked above others. Highly efficient as consumes less time and cost. Uninformed search algorithms do not have additional information about state or search space other than how to traverse the tree, so it is also called blind search. This sort of search approach honestly prevents the algorithms from stumbling approximately the purpose and the direction to the answer. Uninformed/blind search control strategy Do not have additional info about states beyond problem def. Depth-first search, breadth-first search and lowest cost first search are the algorithms come under the category of the uninformed search. Informed Search: Knowledge of the cost of a given node to the goal is in the form of an evaluation function f or h, which assigns a real number to each node. So far we have talked about the uninformed search algorithms which looked through search space for all possible solutions of the problem without having any additional knowledge about search space. Uninformed (blind) search • If a state is not a goal, we cannot tell how close to the goal it might be • Hence, all we can do is move systematically between states until we stumble on a goal • In contrast, informed (heuristic) search uses a guess on how close to the goal a state might be COMP-424, Lecture 2 - January 9, 2013 20 Analysis and Design of The Algorithms Bloxorz problem can be solved using both uninformed search and informed search strategies.
