Listing All Potential Maximal Cliques of a Graph
A potential maximal clique of a graph is a vertex set that induces a maximal clique in some minimal triangulation of that graph. It is known that if these objects can be listed in polynomial time for a class of graphs, the treewidth and the minimum 5ll-in are polynomially tractable for these graphs. We show here that the potential maximal cliques of a graph can be generated in polynomial time i...
متن کاملCounting and Listing all Potential Maximal Cliques of a Graph
We show that the number of potential maximal cliques for an arbitrary graph G on n vertices is O∗(1.8135n), and that all potential maximal cliques can be listed in O∗(1.8899n) time. As a consequence of this results, treewidth and minimum fill-in can be computed in O∗(1.8899n) time.
متن کاملListing all maximal cliques in sparse graphs in near-optimal time
The degeneracy of an n-vertex graph G is the smallest number d such that every subgraph of G contains a vertex of degree at most d. We show that there exists a nearly-optimal fixed-parameter tractable algorithm for enumerating all maximal cliques, parametrized by degeneracy. To achieve this result, we modify the classic Bron–Kerbosch algorithm and show that it runs in time O(dn3d/3). We also pr...
متن کاملListing All Minimal Separators of a Graph
An efficient algorithm listing all minimal vertex separators of an undirected graph is given. The algorithm needs polynomial time per separator that is found.
متن کاملEquations , Maximal Cliques , and Graph Isomorphism
We present a new energy-minimization framework for the graph isomorphism problem which is based on an equivalent maximum clique formulation. The approach is centered around a fundamental result proved by Motzkin and Straus in the mid-1960s, and recently expanded in various ways, which allows us to formulate the maximum clique problem in terms of a standard quadratic program. The attractive feat...
