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. BFS的wikip...

In this passage, we use adjacency lists to represent a graph. Specifically, we define the node of the graph to be the following structure: 1structGraphNode {2intlabel;3vector<GraphNode*>neighbors;4GraphNode(int_label) : label(_label) {}5}; ...

Breadth First Search (BFS) algorithm traverses a graph in a breadthward motion to search a graph data structure for a node that meets a set of criteria. It uses a queue to remember the next vertex to start a search, when a dead end occurs in any iteration....
