Journal ArticleDOI
A survey on pickup and delivery problems: Part II: Transportation between pickup and delivery locations
TL;DR: Single as well as multi vehicle mathematical problem formulations for all three VRPPD types are given, and the respective exact, heuristic, and metaheuristic solution methods are discussed.
Journal ArticleDOI
A survey on pickup and delivery problems
TL;DR: This paper is the first part of a comprehensive survey on pickup and delivery problems and the corresponding exact, heuristic, and metaheuristic solution methods are discussed.
Journal ArticleDOI
Pareto Ant Colony Optimization: A metaheuristic approach to multiobjective portfolio selection
TL;DR: In this article, the authors introduce Pareto Ant Colony Optimization as an especially effective meta-heuristic for solving the portfolio selection problem and compare its performance to other heuristic approaches by means of computational experiments with random instances.
Journal ArticleDOI
D-Ants: savings based ants divide and conquer the vehicle routing problem
TL;DR: This paper presents an algorithm that builds on the Savings based Ant System and enhances its performance in terms of computational effort by decomposing the problem and solving only the much smaller subproblems resulting from the decomposition.
Journal ArticleDOI
A variable neighborhood search heuristic for periodic routing problems
TL;DR: It is shown that slight changes of the proposed VNS procedure is also competitive for the Periodic Traveling Salesman Problem (PTSP), and even outperforms existing solution procedures proposed in the literature.
