Strongly connected components algorithm PDFRSS Strongly connected components (SCC) are the maximally connected subgraphs of a directed graph where every node is reachable from every other node (in other words, there exists a path between every node in the subgraph)....
Following are strongly connected components in given graph 0 1 2 3 4 Time Complexity:The above algorithm calls DFS, fins reverse of the graph and again calls DFS. DFS takes O(V+E) for a graph represented using adjacency list. Reversing a graph also takes O(V+E) time. For reversing the...

Tarjan的极大强连通子图(strongly connected components,SCC)算法基于深度优先遍历(DFS)实现。本文就尝试从深度优先遍历的角度思考一下Tarjan的方法是如何找出SCC的。 深度优先遍历 深度优先遍历可以说是求SCC比较直观的一个途径。例如对于下图来说,我们从A开始遍历,如果能够回到A,那么整个路径就是一个连通分量。例如下图...
An algorithm of linear time complexity is presented to label connected components of a binary image by a quadtree. For a given node, the search for all adjacent nodes is carried out in O(1) (i.e., constant time complexity for the worst case) using our formerly presented algorithm in (...
Connected-component labeling(alternativelyconnected-component analysis,blob extraction,region labeling,blob discovery, orregion extraction) is an algorithmic application ofgraph theory, where subsets ofconnected componentsare uniquelylabeledbased on a givenheuristic.

Algorithm: To cope with the random traversal order of the DFS, Tarjan’s algorithm maintains a stack of valid nodes from which to update low-link values. Nodes are added to the stack of valid nodes as they are explored for the first time. Nodes are removed from the stack each time a ...
