# Which is better BFS or DFS?

## Which is better BFS or DFS?

BFS is better when target is closer to Source. DFS is better when target is far from source. As BFS considers all neighbour so it is not suitable for decision tree used in puzzle games. DFS is more suitable for decision tree.

### What is DFS and BFS?

BFS stands for Breadth First Search. DFS stands for Depth First Search. 2. BFS(Breadth First Search) uses Queue data structure for finding the shortest path. BFS can be used to find single source shortest path in an unweighted graph, because in BFS, we reach a vertex with minimum number of edges from a source vertex.

#### When the Depth First Search of a graph is unique *?

7. When the Depth First Search of a graph is unique? Explanation: When Every node will have one successor then the Depth First Search is unique. In all other cases, when it will have more than one successor, it can choose any of them in arbitrary order.

Where is depth first search used?

Depth-first search is used in topological sorting, scheduling problems, cycle detection in graphs, and solving puzzles with only one solution, such as a maze or a sudoku puzzle. Other applications involve analyzing networks, for example, testing if a graph is bipartite.

What is the purpose of depth first search?

The purpose of Depth First Search (DFS), like Breadth First Search, is to visit every node of a graph and collect some sort of information about how that node was discovered. Like BFS, DFS can be used on both undirected and directed graphs.

## What is DFS AI?

Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking. Example: Question.

### Where is Depth-First Search used?

#### When the Depth First Search of a graph is unique * When the graph is a Binary Tree when the graph is a linked list when the graph is a n ary tree none of the mentioned?

8. When the Depth First Search of a graph is unique? a) When the graph is a Binary Tree b) When the graph is a Linked List c) When the graph is a n-ary Tree d) None of the mentioned Answer: b Explanation: When Every node will have one successor then the Depth First Search is unique.

What is depth first search (DFS)?

Depth First Search (DFS) is the other fundamental graph traversal algorithm; Breadth First Search (BFS) is the other one .

What is depthdepth first search traverses?

Depth First Search Traverses by exploring as far as possible down each path before going back. It is the reason why you may also find this algorithm under the name of Backtracking . Furthermore, This property allows the algorithm to be implemented succinctly in both iterative and recursive forms.

## Is depth first search a good algorithm for pathfinding?

However, please first note that the DFS does not guarantee the shortest path. Then, this is not a very good algorithm if the unique purpose is to do a simple pathfinding. Depth First Search Traverses by exploring as far as possible down each path before going back.

### What is breadth first search (BFS)?

Here is, to be compared, the trace let by the player using a Breadth First Search (BFS) pathfinding algorithm to reach the goal. Depth First Search (DFS) is the other fundamental graph traversal algorithm; Breadth First Search (BFS) is the other one .
