  Abstract: Since its first use by Euler on the seven bridges of K{o}nigsberg problem, graph theory has shown excellent abilities in solving and unveiling the properties of multiple discrete optimization problems notably in communications and signal processing. The study of the structure of integer programs reveals equivalence with graph theory problems, which makes a large body of the literature readily available for solving and characterizing the complexity of these problems. This tutorial presents a framework for utilizing a particular graph theory problem, known as the clique problem, for solving communications and signal processing problems. In particular, the paper aims to illustrate the structural properties of problems that can be formulated as clique problems through multiple examples in communications and signal processing. To that end, the first part of the tutorial formulates and suggests various optimal and heuristic solutions for the clique problem and its variants. The tutorial, further, illustrates the use of the clique formulation and its variants through numerous contemporary examples in communications and signal processing, mainly in maximum access problem for non-orthogonal multiple access networks, throughput maximization using index coding and instantly decodable network coding, collision-free radio frequency identification networks, and resource allocation in cloud-radio access networks. The tutorial finally sheds light on the recent advances of such applications and discusses future research directions on the topics.
