A branch-and-cut algorithm for the target visitation problem
EURO Journal on Computational Optimization - Tập 7 - Trang 209-242 - 2019
In this paper, we consider the target visitation problem (TVP) which arises in the context of disaster treatment. Mathematically speaking, the problem is concerned with finding a route to visit a set of targets starting from and returning to some base. In addition to the distance travelled, a tour is evaluated by taking also preferences into account which address the sequence in which the targets ...... hiện toàn bộ
A modification of the $$\alpha \hbox {BB}$$ method for box-constrained optimization and an application to inverse kinematics
EURO Journal on Computational Optimization - Tập 4 - Trang 93-121 - 2015
For many practical applications it is important to determine not only a numerical approximation of one but a representation of the whole set of globally optimal solutions of a non-convex optimization problem. Then one element of this representation may be chosen based on additional information which cannot be formulated as a mathematical function or within a hierarchical problem formulation. We pr...... hiện toàn bộ

New exact solution approaches for the split delivery vehicle routing problem
EURO Journal on Computational Optimization - Tập 6 - Trang 85-115 - 2017
In this study, we propose exact solution methods for the split delivery vehicle routing problem (SDVRP). We first give a new vehicle-indexed flow formulation for the problem and then a relaxation obtained by aggregating the vehicle-indexed variables over all vehicles. This relaxation may have optimal solutions where several vehicles exchange loads at some customers. We cut off such solutions, in a...... hiện toàn bộ
Portfolio optimization with pw-robustness
EURO Journal on Computational Optimization - Tập 6 - Trang 267-290 - 2018
This paper investigates a portfolio optimization problem under uncertainty on the stock returns, where the manager seeks to achieve an appropriate trade-off between the expected portfolio return and the risk of loss. The uncertainty set consists of a finite set of scenarios occurring with equal probability. We introduce a new robustness criterion, called pw-robustness, which seeks to maximize the ...... hiện toàn bộ

A Lagrangian-ACO matheuristic for car sequencing
EURO Journal on Computational Optimization - Tập 2 - Trang 279-296 - 2014
In this study, we investigate a hybrid Lagrangian relaxation ant colony optimisation for optimisation version of the car sequencing problem. Several cars are required to be scheduled on an assembly line and each car requires a number of options such as sunroof and/or air conditioning. These cars are required to be sequenced such that sub-sequences of specific sizes may only include a limited numbe...... hiện toàn bộ
