强连通图(Strongly Connected Graph): 有向图中,如果任意两个节点之间都存在双向路径,则称图是强连通的。 稀疏图和稠密图: 稀疏图: 边的数量相对较少。 稠密图: 边的数量相对较多。 邻接矩阵和邻接表: 邻接矩阵: 使用矩阵表示节点之间的关系,矩阵元素表示边的存在与否,适用于稠密图。 邻接表: 使用链表或数...
DFS 可以用于检测图中的连通分量,即图中的所有节点是否连通。 defconnected_components(graph):visited=set()components=[]fornodeingraph:ifnodenotinvisited:component=[]dfs_component(graph,node,visited,component)components.append(component)returncomponentsdefdfs_component(graph,node,visited,component):visited.add...
使用DFS来拆分强连通分量的算法实现 主要方法: 参考:https://www.cnblogs.com/LLGemini/p/4725952.html 一些数据类型的定义: Seperate strongly connected components in a directed graph with DFS: 1intMaxIndex(int* v,intsize) {2intmax = v[0];3inti =0;4for(auto it =1; it < size; it++) {5...

A tree is a connected graph without cycles. A rooted tree has a special vertex called the root. A parent of a node v is the last different from v vertex on the path from the root to the vertex v. Children of vertex v are all nodes for which v is the parent. A vertex is a lea...
Here you are asked to solve a simpler similar problem. You have to decide whether a given arbitrary connected graph can be bicolored. That is, if one can assign colors (from a palette of two) to the nodes in such a way that no two adjacent nodes have the same color. To simplify the...
