Nested branch-and-price-and-cut for vehicle routing problems with multiple resource interdependencies

2019

Abstract This paper considers vehicle routing problems (VRPs) with multiple resource interdependencies and addresses the development and computational evaluation of an exact branch-and-price-and-cut algorithm for their solution. An interdependency between two resources means that the two resource consumptions influence one another in such a way that a tradeoff exists between them. This impacts the feasibility and/or the cost of a solution. The subproblem in branch-and-price-and-cut procedures for VRPs is very often a variant of the shortest-path problem with resource constraints (SPPRC). For the exact solution of many SPPRC variants, dynamic-programming based labeling algorithms are predomi…

The Latvian referendum on Russian as a second state language, February 2012

2016

On 18 February 2012 Latvian citizens participated in a referendum on making Russian a second official (“state”) language. The proposal was rejected by three-quarters of voters. There is a complex background to language policy in Latvia, where since regaining independence in 1991 the country has promoted Latvian as the only state language, though Russian and other languages are widely used at a societal level. The language law and associated citizenship law in Latvia (as in Estonia) have received considerable commentary, with recent significant writings disagreeing strongly regarding their interpretation. These laws have also very often been criticized by both European institutions and by Ru…

Rho resonance, timelike pion form factor, and implications for lattice studies of the hadronic vacuum polarization

2020

We study isospin-1 P-wave ππ scattering in lattice QCD with two flavors of O(a) improved Wilson fermions. For pion masses ranging from mπ=265 MeV to mπ=437 MeV, we determine the energy spectrum in the center-of-mass frame and in three moving frames. We obtain the scattering phase shifts using Lüscher’s finite-volume quantization condition. Fitting the dependence of the phase shifts on the scattering momentum to a Breit-Wigner form allows us to determine the corresponding ρ mass mρ and gρππ coupling. By combining the scattering phase shifts with the decay matrix element of the vector current, we calculate the timelike pion form factor, Fπ, and compare the results to the Gounaris-Sakurai repr…

Guía para la incorporación de la perspectiva de género en la docencia en Sociología, Economía y Ciencias Políticas

2019

Sociology has constructed a male worldview that entails a biased interpretation of social reality. For its part, the traditional economy has made invisible the dependence of the commercial sphere of the domestic sphere. And in the field of political science, we also find many gender biases in basic concepts such as justice, equality or citizenship. This article, based on the work done by the authors in the Guia per a una docència universitària amb perspectiva de gènere de Sociologia, Economia i Ciència Política, offers some proposals, teaching resources and consultation tools to introduce the gender perspective in teaching, knowledge transfer and research in these disciplines.

Computing the Original eBWT Faster, Simpler, and with Less Memory

2021

Mantaci et al. [TCS 2007] defined the \(\mathrm {eBWT}\) to extend the definition of the \(\mathrm {BWT}\) to a collection of strings. However, since this introduction, it has been used more generally to describe any \(\mathrm {BWT}\) of a collection of strings, and the fundamental property of the original definition (i.e., the independence from the input order) is frequently disregarded. In this paper, we propose a simple linear-time algorithm for the construction of the original \(\mathrm {eBWT}\), which does not require the preprocessing of Bannai et al. [CPM 2021]. As a byproduct, we obtain the first linear-time algorithm for computing the \(\mathrm {BWT}\) of a single string that uses …
