Dependency Update Adoption Patterns in the Maven Software Ecosystem
Baltasar Berretta, Augustus Thomas, Heather Guarnera
Regular dependency updates protect dependent software components from upstream bugs, security vulnerabilities, and poor code quality. Measures of dependency updates across software…
Fast deterministic algorithms for computing all eccentricities in (hyperbolic) Helly graphs
Feodor F. Dragan, Guillaume Ducoffe, Heather M. Guarnera
A graph is Helly if every family of pairwise intersecting balls has a nonempty common intersection. The class of Helly graphs is the discrete analogue of the class of hyperconvex m…
Injective hulls of various graph classes
Heather M. Guarnera, Feodor F. Dragan, Arne Leitert
A graph is Helly if its disks satisfy the Helly property, i.e., every family of pairwise intersecting disks in G has a common intersection. It is known that for every graph G, ther…
Helly-gap of a graph and vertex eccentricities
Feodor F. Dragan, Heather M. Guarnera
A new metric parameter for a graph, Helly-gap, is introduced. A graph is called -weakly-Helly if any system of pairwise intersecting disks in has a nonempty common inter…
Eccentricity terrain of -hyperbolic graphs
Feodor F. Dragan, Heather M. Guarnera
A graph is -hyperbolic if for any four vertices , the two larger of the three distance sums , , and differ by at…
Eccentricity function in distance-hereditary graphs
Feodor F. Dragan, Heather M. Guarnera
A graph is distance hereditary if every induced path of is a shortest path. In this paper, we show that the eccentricity function in any…
Obstructions to a small hyperbolicity in Helly graphs
Feodor F. Dragan, Heather M. Guarnera
It is known that for every graph there exists the smallest Helly graph into which isometrically embeds ( is called the injective hull of ) such th…
