A branch-price-and-cut method for the min-max k-windy rural postman problem

Given the edges of a graph, the postman problem consists of determining for a vehicle (postman) a shortest route that traverses all edges at least once. Each edge can be traversed in either direction and, when an edge is traversed more than once, the vehicle is said to be deadheading after its first traversal. The rural postman problem is the same as the postman problem except that the edges ar...

Capacitated Windy Rural Postman Problem with Several Vehicles: A Hybrid Multi-Objective Simulated Annealing Algorithm

This paper presents the capacitated Windy Rural Postman Problem with several vehicles. For this problem, two objectives are considered. One of them is the minimization of the total cost of all vehicle routes expressed by the sum of the total traversing cost and another one is reduction of the maximum cost of vehicle route in order to find a set of equitable tours for the vehicles. Mathematical ...

New facets and an enhanced branch-and-cut for the min-max K-vehicles windy rural postman problem

In this paper the Min-Max version of the Windy Rural Postman Problem with several vehicles is introduced. For this problem, in which the objective is to minimize the length of the longest tour in order to find a set of balanced tours for the vehicles, we present here an ILP formulation and study its associated polyhedron. Based on its partial description, a branch-and-cut algorithm has been imp...

Node, Edge, Arc Routing and Turn Penalties: Multiple Problems - One Neighborhood Extension

This article explores a structural neighborhood decomposition for arc routing problems, in which the decisions about traversal orientations during services are made optimally as part of neighbor evaluation procedures. Using memory structures, bidirectional dynamic programming, and lower bounds, we show that a large neighborhood involving classical moves on the sequences of services along with o...

New heuristic algorithms for the windy rural postman problem

In this paper we deal with the Windy Rural Postman Problem. This problem generalizes several important Arc Routing Problems and has interesting real-life applications. Here, we present several heuristics whose study has lead to the design of a Scatter Search algorithm for the Windy Rural Postman Problem. Extensive computational experiments over different sets of instances, with sizes up to 988 ...
