Odd ordering in iterative DFS vs recursive DFS

I\'m solving this dfs/bfs problem. I wrote both an iterative version and a recursive version of DFS.[详细]

Can a depth-first search using a stack return a path to the goal?

I\'d like to use a stack and return a path, but I\'m thinking it\'s not possible. A node must be called directly by its parent so that it can receive the path behind it, whereas when this node is pu[详细]

Edge classification in a DFS

According to the book (Intro to Algorithm), in dfs, edges are classified as 4 kinds: Tree Edge, if in edge (u,v), v is first discovered, then (u, v) is[详细]

depth-first graph search that returns path to goal

I\'ve been trying this all week and cannot, for the life of me, figure it out. I know that I need to have a helper function that will recurse and return pathSoFar. I can\'t seem to get my head around[详细]

BGL DFS Visitor with Priority Queue

I have a tree (in the graph sense) representation of a tree (in the physical sense). The tree is represented as a BGL adjacency list where each vertex contains radius and position properties, i.e., my[详细]

Explanation of runtimes of BFS and DFS

Why are the running times of BFS and DFS O(V+E), especially when there is a node that has a directed edge to a node that can be reached from the vertex, like in this example in the f开发者_运维问答oll[详细]

What's the best way to perform DFS on a very large tree?

Here\'s the situation: The application world consists of hundreds of thousands of states. Given a state, I can work out a set of 3 or 4 other reachable states. A simple recursion can build a tree[详细]
