What is the fringe in the context of search algorithms?
Jul 6, 2019 · 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) …
A* and uniform-cost search are apparently incomplete
Nov 24, 2019 · 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 …
Why is A* optimal if the heuristic function is admissible?
Apr 13, 2018 · 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 …
What are the differences between A* and greedy best-first search?
Aug 30, 2019 · 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 do we use a last-in-first-out queue in depth-first search?
We use the LIFO queue, i.e. stack, for implementation of the depth-first search algorithm because depth-first search always expands the deepest node in the current frontier of the search tree. …
comparison - When should I use Genetic Algorithms as opposed …
Oct 14, 2021 · The paper Comparison between genetic algorithms and particle swarm optimization (1998, by Eberhart and Shi) does not really answer the question of when to use …
What is the space complexity of breadth-first search?
Nov 9, 2020 · 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 …
How does the uniform-cost search algorithm work?
Nov 10, 2019 · 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 …
How is iterative deepening A* better than A*?
The iterative deepening A* search is an algorithm that can find the shortest path between a designated start node and any member of a set of goals. The A* algorithm evaluates nodes by …
Which courses in computer science and logic are relevant to …
Oct 17, 2019 · optionally, courses in logic, but be aware that this is almost a fringe area in AI now, and essentially irrelevant to a PhD in machine learning. The parts you need are usually …
