Mobility offer allocations in corporate settings

open access: yesEURO Journal on Computational Optimization, 2021
Corporate mobility is often based on a fixed assignment of vehicles to employees. Relaxing this fixation and including alternatives such as public transportation or taxis for business and private trips could increase fleet utilization and foster the use ...

Best Polynomial Harmony Search with Best β-Hill Climbing Algorithm

open access: yesJournal of Intelligent Systems, 2020
Harmony Search Algorithm (HSA) is an evolutionary algorithm which mimics the process of music improvisation to obtain a nice harmony. The algorithm has been successfully applied to solve optimization problems in different domains.

A hierarchical approach for solving an integrated packing and sequence-optimization problem in production of glued laminated timber

open access: yesEURO Journal on Computational Optimization, 2020
Integrated packing and sequence-optimization problems appear in many industrial applications. As an example of this type of problem, we consider the production of glued laminated timber (glulam) in sawmills: Wood beams must be packed into a sequence of ...

Solving Single Nesting Problem Using a Genetic Algorithm

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
Since the Bin Packing Problem (BPP) has application to industry and supply chain management problems (to mention only the most important ones), it attracted attention from its formulation.

Ten years of feasibility pump, and counting

open access: yesEURO Journal on Computational Optimization, 2019
The Feasibility Pump (fp) is probably the best-known primal heuristic for mixed-integer programming. The original work by Fischetti et al. (Math Program 104(1):91–104, 2005), which introduced the heuristic for 0–1 mixed-integer linear programs, has been ...

A unified matheuristic for solving multi-constrained traveling salesman problems with profits

open access: yesEURO Journal on Computational Optimization, 2017
In this paper, we address a rich Traveling Salesman Problem with Profits encountered in several real-life cases. We propose a unified solution approach based on variable neighborhood search.

Variable neighborhood search: basics and variants

open access: yesEURO Journal on Computational Optimization, 2017
Variable neighborhood search (VNS) is a framework for building heuristics, based upon systematic changes of neighborhoods both in a descent phase, to find a local minimum, and in a perturbation phase to escape from the corresponding valley. In this paper,

Evaluating balancing on social networks through the efficient solution of correlation clustering problems

open access: yesEURO Journal on Computational Optimization, 2017
One challenge for social network researchers is to evaluate balance in a social network. The degree of balance in a social group can be used as a tool to study whether and how this group evolves to a possible balanced state.

New geometrical compactness measures for zones design

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2012
The design of compact zones has been studied because of its influence in the creation of zones with regular forms, which are easier to analyze, to investigate or to administer.
