Mathematical formulations and metaheuristics comparison for the Push-Tree Problem

The Push-Tree Problem is a recently addressed optimization problem, with the aim to minimize the total amount of traffic generated on information broadcasting networks by a compromise between the use

Exact and metaheuristic approaches to extend lifetime and maintain connectivity in wireless sensors networks

Wireless sensor networks involve a large area of real-world contexts, such as national security, military and environmental control applications, traffic monitoring, among others.

Extending Lifetime Through Partial Coverage And Roles Allocation in Connectivity-Constrained Sensor Networks

We consider a scenario in which certain target locations are monitored through sensors, which are scattered all over a considered area.

Prolonging lifetime in wireless sensor networks with interference constraints

In this work, we consider a scenario in which we have to monitor some locations of interest in a geographical area by means of a wireless sensor network.

Column Generation Embedding Carousel Greedy for the Maximum Network Lifetime Problem with Interference Constraints

We aim to maximize the operational time of a network of sensors, which are used to monitor a predefined set of target locations.

Maximizing Lifetime for a Zone Monitoring Problem Through Reduction to Target Coverage

We consider a scenario in which it is necessary to monitor a geographical region of interest through a network of sensing devices.

The knapsack problem with forfeits

In this paper we introduce and study the Knapsack Problem with Forfeits.

Comparing home and parcel lockers delivery'systems: a math-heuristic approach

E-commerce is a continuously growing sector worldwide, with important repercussions on the delivery system in urban areas and especially in the Business to Consumer (B2C) sector.

AMG4PSBLAS Linear Algebra Package brings Alya one step closer to Exascale

In this work, we interfaced to the Alya code the development version of a software framework for efficient and reliable solution of the sparse linear systems for computation of the pressure field at e

Epidemics in a Synthetic Urban Population with Multiple Levels of Mixing

Network-based epidemic models that account for heterogeneous contact patterns are extensively used to predict and control the diffusion of infectious diseases.
