Maximal strongly connected cliques in directed graphs: Algorithms and bounds
Autor: Alessio Conte, Kunihiro Wasa, Takeaki Uno, Mamadou Moustapha Kanté
Publikováno v: Discrete Applied Mathematics
Discrete Applied Mathematics, 2021, 303, pp.237-252. ⟨10.1016/j.dam.2020.05.027⟩
Finding communities in the form of cohesive subgraphs is a fundamental problem in network analysis. In domains that model networks as undirected graphs, communities are generally associated with dense subgraphs, and many community models have been pr

Given a set P of n points on which facilities can be placed and an integer k, we want to place k facilities on some points so that the minimum distance between facilities is maximized. The problem is called the k-dispersion problem. In this paper we

Publikováno v: The Journal of Supercomputing. 77:4375-4388
During a disaster, social media can be both a source of help and of danger: Social media has a potential to diffuse rumors, and officials involved in disaster mitigation must react quickly to the spread of rumor on social media. In this paper, we inv
