BFS & amp; DFS - What summit to start?
advertisements
I've read pages and pages of information on BFS and DFS algorithms. What none of them say, is which vertex to choose first?
For instance, in this image, do the arrows mean you cannot traverse from c to b, but can traverse from b to c?
Your help is much appreciated, friends.
If it's not a directed graph, it doesn't matter. The graph you posted is a directed graph which means exactly what you've stated. You can go from a to b but not from b to a.
Regarding which node to choose in a directed graph, every node you'll choose can produce different result. Usually under these circumstances it's best to start from the root node if it's given.

How to build a tree with its BFS and DFS traversal
I have the BFS and DFS traversal of a tree. How can I reconstruct the tree from these traversals? For example: BFS Traversal : 4 3 5 1 2 8 7 6 DFS Traversal : 4 3 1 7 2 6 5 8 then the tree would be like bellow: 4 / \ 3 5 / \ \ 2 1 8 | | 6 7 This is o

Find a cycle in a directed graph using BFS or DFS
I tried looking around the Internet but I'm a little stuck at the moment with regards to modifying the BFS or DFS algorithm in order to be able to find a cycle in a directed graph. If the graph were not directed, the DFS algorithm would solve this us
Difference between BFS and DFS
I am reading about DFS in Introduction to Algorithms by Cormen. Following is text snippet. Unlike BFS, whose predecessor subgraph forms a tree, the predecessor subgrpah produced by DFS may be composed of several trees, because search may be repeated
I can not understand how Prolog knows what is the start state in a DFA acceptance rule
I worded the title the best way I could think of, but let me make it clear. When programming a DFA in Prolog, here is a typical manner of doing so: start(q0). final(q2). transition(q0, a, q1). transition(q1, b, q1). transition(q1, c, q2). accept(Symb
