1 Published in 2023 at "IEEE Computer Graphics and Applications"

DOI: 10.1109/mcg.2023.3248289

Abstract: Existing dynamic weighted graph visualization approaches rely on users’ mental comparison to perceive temporal evolution of dynamic weighted graphs, hindering users from effectively analyzing changes across multiple timeslices. We propose DiffSeer, a novel approach for… read more here.

DOI: 10.1177/1729881419846739

Abstract: In this article, we consider the problem of using multiple robots (searchers) to capture intruders in an environment. Assume that a robot can access the position of an intruder in real time, that is, an… read more here.

DOI: 10.1371/journal.pone.0283857

Abstract: We propose a new model to detect the overlapping communities of a network that is based on cooperative games and mathematical programming. More specifically, communities are defined as stable coalitions of a weighted graph community… read more here.

1 Published in 2023 at "Axioms"

DOI: 10.3390/axioms12030247

Abstract: We prove a version of the Ekeland Variational Principle (EkVP) in a weighted graph G and its equivalence to Caristi fixed point theorem and to the Takahashi minimization principle. The usual completeness and topological notions… read more here.

1 Published in 2021 at "Symmetry"

DOI: 10.3390/sym13050902

Abstract: Establishing a node importance ranking is a problem that has attracted the attention of many researchers in recent decades. For unweighted networks where the edges do not have any attached weight, many proposals have been… read more here.
