Branch‐cut cosmology and the Bekenstein Criterion

open access: yesAstronomische Nachrichten, 2022
AbstractIn this contribution, we address the implications of the Bekenstein Criterion in the branch‐cut cosmology. The impossibility of packaging energy and entropy according to the Bekenstein Criterion in a finite size makes the transition phase of the branch‐cut cosmology very peculiar, imposing a topological leap between the contraction and ...

A Wheeler–DeWitt Non-Commutative Quantum Approach to the Branch-Cut Gravity

open access: yesUniverse, 2023
In this contribution, motivated by the quest to understand cosmic acceleration, based on the theory of Hořava–Lifshitz and on the branch-cut gravitation, we investigate the effects of non-commutativity of a mini-superspace of variables obeying the ...

Computational Recognition of RNA Splice Sites by Exact Algorithms for the Quadratic Traveling Salesman Problem

open access: yesComputation, 2015
One fundamental problem of bioinformatics is the computational recognition of DNA and RNA binding sites. Given a set of short DNA or RNA sequences of equal length such as transcription factor binding sites or RNA splice sites, the task is to learn a ...

Optimizing the Strategic Decisions for One-Way Station-Based Carsharing Systems: A Mean-CVaR Approach

open access: yesIEEE Access, 2021
The study focuses on the strategic decisions including on the location and capacity of stations and the fleet size for designing the one-way station-based carsharing systems. Under demand uncertainty, we introduce a two-stage risk-averse stochastic model

An Effective Branch-and-cut algorithm in Order to Solve the Mixed Integer Bi-level Programming

open access: yesInternational Journal of Production Management and Engineering, 2017
In this paper, a new branch-and-cut algorithm for mixed integer bi-level programming is proposed. For achieving this purpose, a historical perspective of the development of enumeration methods in the field of bi-level linear programming is considered ...

Cutting the Coon amplitude

open access: yesJournal of High Energy Physics, 2023
The Coon amplitude is a q-deformed generalization of the Veneziano amplitude exhibiting a semi-infinite sequence of poles that converge on an accumulation point, from which a branch cut emerges. A number of recent papers have provided compelling evidence

A Branch-and-Cut Algorithm for the Multilevel Generalized Assignment Problem

open access: yesIEEE Access, 2013
The multilevel generalized assignment problem (MGAP) consists of minimizing the assignment cost of a set of jobs to machines, each having associated therewith a capacity constraint.

Separating valid odd-cycle and odd-set inequalities for the multiple depot vehicle scheduling problem

open access: yesEURO Journal on Computational Optimization, 2013
We consider the multicommodity network flow formulation of the multiple depot vehicle scheduling problem (MDVSP) and investigate several strategies within a branch-and-cut framework for solving the MDVSP.
