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) space is …
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?
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 it from the fringe.
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 the cost of its …
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 …
reinforcement learning - Is Clipping Necessary for PPO? - Artificial ...
Nov 24, 2025 · I believe I have a decent understanding of PPO, but I also feel that it could be stated in a simpler, more intuitive way that does not involve the clipping function. That makes me wonder if there is
What is the Turing test? - Artificial Intelligence Stack Exchange
