What is the fringe in the context of search algorithms?
2019年7月6日 · 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 …
A* and uniform-cost search are apparently incomplete
2019年11月24日 · The evaluation function is used to choose the next node to visit from the fringe, which is the set of nodes that can potentially be visited. Whenever we visit a node, we remove it from the …
What are the differences between A* and greedy best-first search?
2019年8月30日 · What are the differences between the A* algorithm and the greedy best-first search algorithm? Which one should I use? Which algorithm is the better one, and why?
Why is A* optimal if the heuristic function is admissible?
2018年4月13日 · 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 …
What is the space complexity of breadth-first search?
2020年11月9日 · The space complexity of the breadth-first search algorithm is O(bd O (b d) in the worst case, and it corresponds to the largest possible number of nodes that may be stored in the frontier at …
How does the uniform-cost search algorithm work?
2019年11月10日 · 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 …
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 …
