This paper proposes a new method for finding all maximum cliques of an undirected graph.It is based on some properties of the interval graph and a specific one dimensional assignment algorithm.Although the algorithm is heuristic,it can obtain exact solutions.The algorithm is especially efficient for...

Algorithmic Graph Theory and Perfect Graphs Theorem 9.6 Gn, k is not a comparability graph, for 1 ≤ k≤ n –2. Proof Recall that an undirected graph is a comparability graph if and only if every closed path with no triangular chords has even length (see Theorem 5.27). However, [a0,a1...

For a directed graph, connectivity is further classified into “strong connectiv...
bit_gossip, named after its implementation technique, is a simple pathfinding library for calculating all node pairs' shortest paths in an unweighted undirected graph.Once the computation is complete, you can retrieve the shortest path between any two nodes in near constant time; I'm talking less...
