Designer-driven 3D buildings generated using Variable Neighborhood Search [PDF]

open access: yes2014 IEEE Conference on Computational Intelligence and Games, 2014
This paper presents a mechanism to generate virtual buildings considering designer constraints and guidelines. This mechanism is implemented as a pipeline of different Variable Neighborhood Search (VNS) optimization processes in which several subproblems are tackled (1) rooms locations, (2) connectivity graph, and (3) element placement.

Variable Neighborhood Search [PDF]

open access: yesComputers & Operations Research, 1997
Variable neighborhood search (VNS) is a metaheuristic for solving combinatorial and global optimization problems. Its basic idea is systematic change of neighborhood both within a descent phase to find a local optimum and in a perturbation phase to get out of the corresponding valley.

A variable neighborhood search simheuristic for project portfolio selection under uncertainty [PDF]

open access: yes, 2018
With limited nancial resources, decision-makers in rms and governments face the task of selecting the best portfolio of projects to invest in. As the pool of project proposals increases and more realistic constraints are considered, the problem becomes

Primal-dual variable neighborhood search for the simple plant-location problem [PDF]

open access: yes, 2007
Copyright @ 2007 INFORMSThe variable neighborhood search metaheuristic is applied to the primal simple plant-location problem and to a reduced dual obtained by exploiting the complementary slackness conditions.

On Neighborhood Tree Search [PDF]

open access: yes, 2012
We consider the neighborhood tree induced by alternating the use of different neighborhood structures within a local search descent. We investigate the issue of designing a search strategy operating at the neighborhood tree level by exploring different ...

Fitting censored quantile regression by variable neighborhood search [PDF]

open access: yes, 2015
Quantile regression is an increasingly important topic in statistical analysis. However, fitting censored quantile regression is hard to solve numerically because the objective function to be minimized is not convex nor concave in regressors. Performance

Bringing order into the neighborhoods: relaxation guided variable neighborhood search [PDF]

open access: yesJournal of Heuristics, 2007
In this article we investigate a new variant of Variable Neighborhood Search (VNS): Relaxation Guided Variable Neighborhood Search. It is based on the general VNS scheme and a new Variable Neighborhood Descent (VND) algorithm. The ordering of the neighborhood structures in this VND is determined dynamically by solving relaxations of them. The objective

Una comparación de algoritmos basados en trayectoria granular para el problema de localización y ruteo con flota heterogénea (LRPH) [PDF]

open access: yes, 2017
Indexación: Scopus.We consider the Location-Routing Problem with Heterogeneous Fleet (LRPH) in which the goal is to determine the depots to be opened, the customers to be assigned to each open depot, and the corresponding routes fulfilling the demand of ...
