“rsppfp”: An R package for the shortest path problem with forbidden paths

open access: yesSoftwareX, 2019
The Shortest Path Problem with Forbidden Paths (SPPFP) is a variant of the original shortest path problem, where the constraints come from a set of forbidden arc sequences that cannot be part of any feasible solution.

Erdős–Szekeres Theorem for Point Sets with Forbidden Subconfigurations [PDF]

open access: yesDiscrete & Computational Geometry, 2012
According to the Erdős-Szekeres theorem, \(4^n\) points in the plane in general position contain some \(n\) points in convex position. How many points will imply the existence of \(n\) points among them in convex position, if we have an extra condition, namely that a certain (fixed) order type does not occur in the point set?

Small clique number graphs with three trivial critical ideals

open access: yesSpecial Matrices, 2018
The critical ideals of a graph are the determinantal ideals of the generalized Laplacian matrix associated to a graph. Previously, they have been used in the understanding and characterizing of the graphs with critical group with few invariant factors ...

Right-jumps and pattern avoiding permutations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2017
We study the iteration of the process "a particle jumps to the right" in permutations. We prove that the set of permutations obtained in this model after a given number of iterations from the identity is a class of pattern avoiding permutations.

Forbidden Sets in Argumentation Semantics [PDF]

open access: yes, 2016
We consider an alternative interpretation of classical Dung argumentation framework (af) semantics by introducing the concept of “forbidden sets”. In informal terms, such sets are well-defined with respect to any extension-based semantics and reflect those subsets of argument that collectively can never form part of an acceptable ...

Geometrical sets with forbidden configurations

open access: yesForum of Mathematics, Sigma, 2023
Abstract Given finite configurations $P_1, \dots , P_n \subset \mathbb {R}^d$ , let us denote by $\mathbf {m}_{\mathbb {R}^d}(P_1, \dots , P_n)$ the maximum density a set $A \subseteq \mathbb {R}^d$ can have without containing congruent copies of any

Search for the C-violating meson decay η → π0e+e− with WASA-at-COSY

open access: yesEPJ Web of Conferences, 2016
TheWASA-at-COSY experiment is, besides meson production processes, dedicated to studies on rare and forbidden decays of light mesons. In extensive η-production beam times, a high-statistics data set have been collected by means of proton-proton ...

The Expressive Creativity of Euphemism and Dysphemism

open access: yesLexis: Journal in English Lexicology, 2012
Euphemism and dysphemism are two cognitive processes of conceptualisation, with countervalent effects (having the same base and resources but different aims and purposes), of a certain forbidden reality.
