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

New variable neighborhood search method for minimum sum coloring problem on simple graphs [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2018
The minimum sum coloring problem (MSCP) is to find a legal vertex coloring for G using colors represented by natural numbers (1,2, . . .) such that the total sum of the colors assigned to the vertices is minimized. The aim of this paper is to present the
