A Note on Ultrametric Spaces, Minimum Spanning Trees and the Topological Distance Algorithm

open access: yesInformation, 2020
We relate the definition of an ultrametric space to the topological distance algorithm—an algorithm defined in the context of peer-to-peer network applications.

Interaction graphs: Graphings

open access: yesAnnals of Pure and Applied Logic, 2017
In two previous papers, we exposed a combinatorial approach to the program of Geometry of Interaction, a program initiated by Jean-Yves Girard. The strength of our approach lies in the fact that we interpret proofs by simpler structures - graphs - than Girard's constructions, while generalizing the latter since they can be recovered as special cases of

Gain Scores, ANCOVA, and Propensity Matching Procedures for Evaluating Treatments in Education

open access: yesOpen Education Studies, 2020
Researchers have several options available to analyze data from interventions when participants have not been randomly allocated into conditions. Among these are the gain score, ANCOVA, and propensity matching procedures.

Distance-regular Cayley graphs with small valency

open access: yes, 2019
We consider the problem of which distance-regular graphs with small valency are Cayley graphs. We determine the distance-regular Cayley graphs with valency at most $4$, the Cayley graphs among the distance-regular graphs with known putative intersection ...

Graphs of Morphisms of Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2008
This is an account for the combinatorially minded reader of various categories of directed and undirected graphs, and their analogies with the category of sets. As an application, the endomorphisms of a graph are in this context not only composable, giving a monoid structure, but also have a notion of adjacency, so that the set of endomorphisms is both

A Novel Similarity Score for Link Prediction Approach Using Financial Transaction Networks and Firms’ Attribute

open access: yesIEEE Access
Financial transaction networks represent inter-firm relationships, where firms and transactions act as nodes and edges, respectively. Link prediction in these networks aims to identify potential future or missing transactions or links, providing valuable

Stochastic model for the process of Wine Award: Visualization and quantification [PDF]

open access: yesCiência e Técnica Vitivinícola, 2014
Sensory analysis is an important part of the process of evaluation of the quality of wines. Nowadays, one of the most used methods for describing this evaluation is the concept of awards.

On Almost Well-Covered Graphs of Girth at Least 6

open access: yes, 2018
We consider a relaxation of the concept of well-covered graphs, which are graphs with all maximal independent sets of the same size. The extent to which a graph fails to be well-covered can be measured by its independence gap, defined as the difference ...
