Depth first search (DFS) tree is a fundamental data structure for solving various problems in graphs. It is well known that it takes O(m+n) time to build a DFS tree for a given undirected graph G = (V, E) on n vertices and m edges. We address the problem of maintaining a DFS ...
一般來說vertex的weight就是等於1 5 基本定義 degree 定義在vertex上 undirectedgraph vertex的degree就等於跟這個vertex相連的edge個數 directedgraph vertex的degree分成兩種 indegree所有指向這個vertex的edge個數 outdegree所有由這個vertex指出去的edge個數 6 Example ...
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...
directedgraph vertex的degree分成兩種 indegree 所有指向這個vertex的edge個數 outdegree 所有由這個vertex指出去的edge個數 undirected directed Example 建議 當看到一個題目時,如果是graph上的題目或是要轉成graph來做的題目的話,首先要判斷這個graph是directed或undirected,是weighted或unweighted,是不是一些比較特殊的gr...

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}; ...
