Finding strongly connected components in distributed graphs
The traditional, serial, algorithm for finding the strongly connected components in a graph is based on depth first search and has complexity which is linear in the size of the graph. Depth first search is difficult to parallelize, which creates a need for a different parallel algorithm for this problem. We describe the implementation of a recently proposed parallel algorithm that finds strongl...
متن کاملStrongly connected components-Algorithm for finding the strongly connected components of a graph
A directed graph G (V, E) is strongly connected if and only if, for any pair of vertices X and Y from V, there exists a path from X to Y and a path from Y to X. In Computer Science, the partition of a graph in strongly connected components is represented by the partition of all vertices from the graph, so that for any two vertices, X and Y, from the same partition, there exists a path from X to...
متن کاملOn Finding the Strongly Connected Components in a Directed Graph
We present two improved versions of Tarjan's algorithm for the detection of strongly connected components in a directed graph. Our new algorithms handle sparse graphs and graphs with many trivial components (containing only one node) more economically than Tarjan's original algorithm. As an application we present an eecient transitive closure algorithm.
متن کاملA space-efficient algorithm for finding strongly connected components
Tarjan’s algorihm for finding the strongly connected components of a directed graph is widely used and acclaimed. His original algorithm required at most v(2 + 5w) bits of storage, where w is the machine’s word size, whilst Nuutila and Soisalon-Soininen reduced this to v(1 + 4w). Many real world applications routinely operate on very large graphs where the storage requirements of such algorithm...
متن کاملTwinless Strongly Connected Components
Tarjan [9], describes how depth first search can be used to identify Strongly Connected Components (SCC) of a directed graph in linear time. It is standard to study Tarjan’s SCC algorithm in most senior undergraduate or introductory graduate computer science algorithms courses. In this paper we introduce the concept of a twinless strongly connected component (TSCC) of a directed graph. Loosely ...
