NLP.py is a programming environment to model continuous optimization problems and to design computational methods in the high-level and powerful Python l...

We study a rich production-routing problem with time windows arising at a catering services company. The production part consists of assembling the meals to ...

The geometric-arithmetic index \(GA\) of a graph \(G\) is the sum of ratios, over all edges of \(G\), of the geometric mean to the arithmetic mean of t...

In the present paper, we prove lower and upper bounds for each of the ratios \(GA/\delta\), \(GA/\overline{d}\) and \(\Delta\), in terms of the order `...

In the present paper, we compare the geometric-arithmetic index \(GA\) and the chromatic number \(\chi\) of a connected graph with given order. We prove,...

In this paper we propose a new variant of the Variable Neighborhood Decomposition Search (VNDS) heuristic for solving global optimization problems and apply ...

Driven by the need of robust, cost-effective, and ready-to-use solutions to connect wirelessly thousands to million of nodes, an increasing number of applica...

This work presents Visual PeRF-Mesh, a tool that addresses the performance analysis and simulation of Advanced Metering Infrastructure (AMI) RF-mesh smart...

Due to the limited applicability of the classical job shop scheduling problem in practice, many researchers have been addressing more complex versions of thi...

In this paper, we propose a new scheme for building algorithms to detect communities in networks. This new approach is based upon a vertex centrality measur...

Extreme Learning Machine (ELM) has recently increased popularity and has been successfully applied to a wide range of applications. Variants using regulariza...

The technological developments observed in the last two decades contributed to the digitalization of products and the introduction of devices to consume th...

An electronic nose (e-nose) is a device that analyzes the chemical components of an odour. The e-nose consists of an array of gas sensors for chemical detect...

In this article we consider a real-world problem submitted to us by the Hatch company. This problem consists of designing a collection network for a wind f...

Scheduling activities in an underground mine is a very complex task. This paper presents an optimization model for short-term planning that takes into consid...

Given a graph \(G=(V,E)\) with a root \(r\in V\), positive capacities \(\{c(e) | e\in E\}\), and non-negative lengths \(\{\ell(e) | e\in E\}\), the m...

Positron emission tomography (PET) image reconstruction in the presence of periodic motion, such as heartbeat and breathing, has been actively investigated ...

Automatic programming is an efficient technique that has contributed to an important development in the artificial intelligence field. In this paper, we intr...

One of the most complex early-exercise decisions faced by traders in the financial derivatives markets is with T-Bond futures, due to the combination of mu...

Let \(\gamma(G)\) and \(\iota(G)\) be the domination and independent domination numbers of a graph \(G\), respectively. Introduced by Sumner and Moorer...
