Locating Objects in the Plane Using Global Optimization Techniques
(Informs, 2009-10-07)
We address the problem of locating objects in the plane such as segments, arcs of circumferences, arbitrary convex sets, their complements or their boundaries. Given a set of points, we seek the rotation and translation ...

Variable selection in classification for multivariate functional data
(ELSEVIER SCIENCE INC, 2019-05-01)
When classification methods are applied to high-dimensional data, selecting a subset of the predictors may lead to an improvement in the predictive ability of the estimated model, in addition to reducing the model complexity. ...

Inferring efficient weights from pairwise comparison matrices
(Springer, 2006-10)
Several multi-criteria-decision-making methodologies assume the existence of weights associated with the different criteria, reflecting their relative importance.One of the most popular ways to infer such weights is the ...

Gaussian variable neighborhood search for continuous optimization
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-01-01)
Variable Neighborhood Search (VNS) has shown to be a powerful tool for solving both discrete and box-constrained continuous optimization problems. In this note we extend the methodology by allowing also to address unconstrained ...

Optimal cluster selection probabilities to estimate the finite population distribution function under PPS cluster sampling
(Springer, 2002-06)
We study the estimation of the finite population distribution function under several sampling strategies based on a PPS cluster sampling, that is to say, with cluster selection probabilities proportional to size. For the ...
