Formulations and exact algorithms for the distance-constrained generalized directed rural postman problem

open access: yesEURO Journal on Computational Optimization, 2017
The generalized directed rural postman problem is an arc routing problem with many interesting real-life applications, such as routing for meter reading. In this application, a vehicle with a receiver travels through a series of neighborhoods.

Engineering Branch-and-Cut Algorithms for the Equicut Problem [PDF]

open access: yes, 2013
A minimum equicut of an edge-weighted graph is a partition of the nodes of the graph into two sets of equal size such that the sum of the weights of edges joining nodes in different partitions is minimum. We compare basic linear and semidefinite relaxations for the equicut problem, and find that linear bounds are competitive with the corresponding ...

Mathematical Modeling and Optimal Blank Generation in Glass Manufacturing

open access: yesJournal of Applied Mathematics, 2014
This paper discusses the stock size selection problem (Chambers and Dyson, 1976), which is of relevance in the float glass industry. Given a fixed integer N, generally between 2 and 6 (but potentially larger), we find the N best sizes for intermediate ...

A branch-and-cut algorithm for multiple sequence alignment

open access: yesProceedings of the first annual international conference on Computational molecular biology - RECOMB '97, 1997
We consider a branch-and-cut approach for solving the multiple sequence alignment problem, which is a central problem in computational biology. We propose a general model for this problem in which arbitrary gap costs are allowed. An interesting aspect of our approach is that the three (exponentially large) classes of natural valid inequalities that we ...

Branch-and-Cut-and-Price algorithms for the preemptive RCPSP [PDF]

open access: yesRAIRO - Operations Research, 2018
In this article, we address the preemptive Resource-Constrained Precedence Scheduling Problem. We propose two mixed integer formulations containing an exponential number of variables and inequalities. An antichain is a set of pairwise incomparable elements with respect to the precedence constraints.

A Comparison of Algorithms for Finding an Efficient Theme Park Tour

open access: yesJournal of Applied Mathematics, 2018
The problem of efficiently touring a theme park so as to minimize the amount of time spent in queues is an instance of the Traveling Salesman Problem with Time-Dependent Service Times (TSP-TS). In this paper, we present a mixed-integer linear programming

A branch‐and‐cut algorithm for the ring spur assignment problem [PDF]

open access: yesNetworks, 2013
AbstractThe ring spur assignment problem arises in the design of next‐generation telecommunications networks and has applications in location‐allocation problems. The aim is to identify a minimum cost set of interconnected ring spurs. We seek to connect all nodes of the network either on a set of bounded disjoint local rings or by a single spur edge ...
