- 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
- A* and uniform-cost search are apparently incomplete
Stack Exchange Network Stack Exchange network consists of 183 Q A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers
- 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 combining the
- Why is A* optimal if the heuristic function is admissible?
The tree search does not remember which states it has already visited, only the "fringe" of states it hasn't visited yet A graph search is a general search strategy for searching graph-structured problems, where it's possible to double back to an earlier state, like in chess (e g both players can just move their kings back and forth)
- norvig russell - What does the statement with the max do in the . . .
By taking the max, the code ensures that states that are restored maintain at least the cost of the previously best unexpanded state (If the g+h cost is larger, then we know the state wasn't previously expanded and it wasn't previously the state on the fringe with the minimum edge cost )
- How does the uniform-cost search algorithm work?
Uniform Cost Search is also called the Cheapest First Search For an example and entire explanation you can directly go to this link: Udacity - Uniform Cost Search
- 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
- game ai - Artificial Intelligence Stack Exchange
I have extensively researched now for three days straight trying to find which algorithm is better in terms of which algorithm uses up more memory I know uninformed algorithms, like depth-first se
