What is the fringe in the context of search algorithms? In English, the fringe is (also) defined as the outer, marginal, or extreme part of an area, group, or sphere of activity In the context of AI search algorithms, the state (or search) space is usually represented as a graph, where nodes are states and the edges are the connections (or actions) between the corresponding states
Why is A* optimal if the heuristic function is admissible? A heuristic is admissible if it never overestimates the true cost to reach the goal node from n n If a heuristic is consistent, then the heuristic value of n n is never greater than the cost of its successor, n′ n, plus the successor's heuristic value Why is A*, using tree or graph searches, optimal, if it uses an admissible heuristic?
What is the Turing test? - Artificial Intelligence Stack Exchange According to Wikipedia The "standard interpretation" of the Turing test, in which player C, the interrogator, is given the task of trying to determine which player – A or B – is a computer and which is a human The interrogator is limited to using the responses to written questions to make the determination
What is the difference between tree search and graph search? There is always a lot of confusion about this concept, because the naming is misleading, given that both tree and graph searches produce a tree (from which you can derive a path) while exploring the search space, which is usually represented as a graph Differences Firstly, we have to understand that the underlying problem (or search space) is almost always represented as a graph (although the
How does the uniform-cost search algorithm work? What is the uniform-cost search (UCS) algorithm? How does it work? I would appreciate seeing a graphical execution of the algorithm How does the frontier evolve in the case of UCS?
