Optimizing C-RAN backhaul topologies: A resilience-oriented approach using graph invariants
Trends in wireless networks are proceeding toward increasingly dense deployments, supporting resilient interconnection for applications that carry ever highe...
BibTeX referenceFirm-specific credit risk modelling in the presence of statistical regimes and noisy prices
Security prices are important inputs for estimating credit risk models. Yet, to obtain an accurate firm-specific credit risk assessment, one needs a reliable...
BibTeX referenceRobust optimization of noisy blackbox problems using the Mesh Adaptive Direct Search algorithm
Blackbox optimization problems are often contaminated with numerical noise, and direct search methods such as the Mesh Adaptive Direct Search (MADS) algorit...
BibTeX reference
The authors investigate the complexity needed in the structure of the scenario trees to maximize energy production in a rolling-horizon framework. Three comp...
BibTeX reference
We present a new derivative-free trust-region (DFTR) algorithm to solve general nonlinear constrained problems with the use of an augmented Lagrangian m...
BibTeX reference
This paper presents a new high-order, non-stationary sequential simulation approach, aiming to deal with the typically complex, curvilinear structures and hi...
BibTeX reference
This paper examines the issue of price and advertising coordination in bilateral monopolies from a dynamic perspective. Its main objectives are to design i...
BibTeX reference
We study derivative-free constrained optimization problems and propose a trust-region method that builds linear or quadratic models around the best feasible ...
BibTeX referenceDynamic programming and parallel computing for valuing two-dimensional american-style options
We propose a dynamic program coupled with finite elements for valuing two-dimensional American-style options. To speed-up our procedure, we use parallel comp...
BibTeX reference
Airline crew scheduling is typically performed in two steps : crew pairing followed by crew assignment. The crew pairing problem (CPP) finds a set of pairing...
BibTeX reference
We consider within the framework of Mean Field Games theory a dynamic discrete choice model with an advertiser, where a large number of minor agents (e.g., c...
BibTeX referenceDynamic collective choice: Social optima
We consider a dynamic collective choice problem where a large number of players are cooperatively choosing between multiple destinations while being influenc...
BibTeX reference
In this paper we consider an interactive communication system with two users, who sequentially observe two correlated sources, and send the quantized observa...
BibTeX reference
An augmented Lagrangian (AL) can convert a constrained optimization problem into a sequence of simpler (e.g., unconstrained) problems, which are then usual...
BibTeX reference
NLP.py is a programming environment to model continuous optimization problems and to design computational methods in the high-level and powerful Python l...
BibTeX referenceA Branch-Price-and-Cut algorithm for a production-routing problem with short-lifespan products
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 ...
