Abstract The Orienteering Problem (OP) has received a lot of attention in the past few
decades. The OP is a routing problem in which the goal is to determine a subset of nodes to …

In the last years, Multi-Robot Systems (MRS) have experienced considerable recognition
due to various possible real-world applications. Multi-Robot Task Allocation (MRTA) is …

Green Logistics has emerged as the new agenda item in supply chain management. The
traditional objective of distribution management has been upgraded to minimizing system …

Abstract Recommender Systems (RSs) have been extensively utilized as a means of

During the last decade, a number of challenging applications in logistics, tourism and other
fields were modelled as orienteering problems (OP). In the orienteering problem, a set of …

The attributes of vehicle routing problems are additional characteristics or constraints that
aim to better take into account the specificities of real applications. The variants thus formed …

Previous work on assigning tasks to robots has proposed extensive categorizations of
allocation of tasks with and without constraints. The main contribution of this paper is a …

The tourist trip design problem (TTDP) refers to a route-planning problem for tourists
interested in visiting multiple points of interest (POIs). TTDP solvers derive daily tourist tours …

Major advances were recently obtained in the exact solution of vehicle routing problems
(VRPs). Sophisticated branch-cut-and-price (BCP) algorithms for some of the most classical …

Traveling salesman problems with profits (TSPs with profits) are a generalization of the
traveling salesman problem (TSP), where it is not necessary to visit all vertices. A profit is …
