Linear Algebra and Its Applications, 2012 The study of a mixed graph and its Laplacian matrix have gained quite a bit of interest among the researchers. Mixed graphs are very important for the study of graph theory as they provide a setup where one can have directed and undirected edges in the ...

The outflow ranking method for weighted directed graphs [PDF]
European Journal of Operational Research, 2009 A ranking method assigns to every weighted directed graph a (weak) ordering of the nodes. In this paper we axiomatize the ranking method that ranks the nodes according to their outflow using four independent axioms.

Cheeger Inequalities for General Edge-Weighted Directed Graphs [PDF]
Lecture Notes in Computer Science, 2015 We consider Cheeger Inequalities for general edge-weighted directed graphs. Previously the directed case was considered by Chung for a probability transition matrix corresponding to a strongly connected graph with weights induced by a stationary ...

Adjasankey: Visualization of Huge Hierarchical Weighted and Directed Graphs [PDF]
2015 19th International Conference on Information Visualisation, 2015 International audienceVisualization of hierarchical weighted and directed graphs are usually done with node-link or adjacency matrix diagrams. However, these representations suffer from various drawbacks: low readability in a context of Big Data, high ...

Weighted Consensus Problem for Multiagent Systems with Edge- and Node-Weighted Directed Graphs
Complexity, 2019 In this paper, the concept of consensus is generalized to weighted consensus, by which the conventional consensus, the bipartite consensus, and the cluster consensus problems can be unified in the proposed weighted consensus frame. The dynamics of agents

On the Graph Isomorphism Completeness of Directed and Multidirected Graphs
MathematicsThe category of directed graphs is isomorphic to a particular category whose objects are labeled undirected bipartite graphs and whose morphisms are undirected graph morphisms that respect the labeling. Based on this isomorphism, we begin by showing that

Drawing Large Weighted Graphs Using Clustered Force-Directed Algorithm [PDF]
, 2014 © 2014 IEEE. Clustered graph drawing is widely considered as a good method to overcome the scalability problem when visualizing large (or huge) graphs. Force-directed algorithm is a popular approach for laying graphs yet small to medium size datasets due
