چکیده

Given two graphs, a fundamental task faced by matching algorithms consists of computing either the (Connected) Maximal Common Induced Subgraphs ((C)MCIS) or the (Connected) Maximal Common Edge Subgraphs ((C)MCES). In particular, computing the CMCIS or CMCES reduces to reporting so-called connected cliques in product graphs, a problem for which an algorithm has been presented in a recent paper I. Koch, TCS 250 (1-2), 2001. This algorithm suffers from two problems which are corrected in this note.

A note on the problem of reporting maximal cliques

Reporting the maximal cliques of a graph is a fundamental problem arising in many areas. This note bridges the gap between three papers addressing this problem: the original paper of Bron–Kerbosh [C. Bron, J. Kerbosch, Algorithm 457: Finding all cliques of an undirected graph, Communication of ACM 16 (9) (1973) 575–577], and two papers recently published in TCS, namely that of Tomita et al. [To...

Linear-Time Enumeration of Isolated Cliques

For a given graph G of n vertices and m edges, a clique S of size k is said to be c-isolated if there are at most ck outgoing edges from S. It is shown that this parameter c is an interesting measure which governs the complexity of finding cliques. In particular, if c is a constant, then we can enumerate all c-isolated maximal cliques in linear time, and if c = O(log n), then we can enumerate a...

Extracting of All Maximal Cliques: Monotone System Approach

NP-complicated problems have been described in the graph theory. An example is the extracting of all maximal cliques from a graph. Many algorithms for solving this problem have been described. However, complexity is linear to the number of maximal cliques. This paper discusses a new approach for extracting maximal cliques, based on the monotone system theory. The complexity of the presented alg...

The Parallel Maximal Cliques Algorithm for Protein Sequence Clustering

Problem statement: Protein sequence clustering is a method used to discover relations between proteins. This method groups the proteins based on their common features. It is a core process in protein sequence classification. Graph theory has been used in protein sequence clustering as a means of partitioning the data into groups, where each group constitutes a cluster. Mohseni-Zadeh introduced ...

The Worst-Case Time Complexity for Generating All Maximal Cliques

We present a depth-first search algorithm for generating all maximal cliques of an undirected graph, in which pruning methods are employed as in the Bron–Kerbosch algorithm. All the maximal cliques generated are output in a tree-like form. Subsequently, we prove that its worst-case time complexity is O(3n/3) for an n-vertex graph. This is optimal as a function of n, since there exist up to 3n/3...
