• Tarjan's strongly connected components algorithm — Tarjan s Algorithm (named for its discoverer, Robert Tarjan) is a graph theory algorithm for finding the strongly connected components of a graph. It can be seen as an improved version of Kosaraju s algorithm, and is comparable in efficiency to… …   Wikipedia

• Connected component (graph theory) — A graph with three connected components. In graph theory, a connected component of an undirected graph is a subgraph in which any two vertices are connected to each other by paths, and which is connected to no additional vertices. For example,… …   Wikipedia

• Web of trust — For the internet security website, see WOT: Web of Trust. In cryptography, a web of trust is a concept used in PGP, GnuPG, and other OpenPGP compatible systems to establish the authenticity of the binding between a public key and its owner. Its… …   Wikipedia

• Mean Shortest Distance — In statistical analysis of the PGP/GnuPG/OpenPGP Web of trust the mean shortest distance (MSD) is one measurement of how trusted a given PGP key is within the strongly connected set of PGP keys that make up the Web of trust.Drew Streib wrote the… …   Wikipedia

• Aperiodic graph — In the mathematical area of graph theory, a directed graph is said to be aperiodic if there is no integer k > 1 that divides the length of every cycle of the graph. Equivalently, a graph is aperiodic if the greatest common divisor of the lengths… …   Wikipedia

• Connectivity (graph theory) — In mathematics and computer science, connectivity is one of the basic concepts of graph theory: it asks for the minimum number of elements (nodes or edges) which need to be removed to disconnect the remaining nodes from each other[1]. It is… …   Wikipedia
