Providing the right data to a machine learning model is an important step to insure the performance of the model. Non-compliant training data instances may l...

BibTeX referenceOn GSOR, the generalized successive overrelaxation method for double saddle-point problems

We consider the generalized successive overrelaxation (GSOR) method for solving a class of block three-by-three saddle-point problems. Based on the necessary...

BibTeX referenceOptimal localizability criterion for positioning with distance-deteriorated relative measurements

Position estimation in Multi-Robot Systems (MRS) relies on relative angle or distance measurements between the robots, which generally deteriorate as dista...

The conjugate gradient (CG) method is a classic Krylov subspace method for solving symmetric positive definite linear systems. We introduce an analogous sem...

BibTeX referenceComputing a sparse projection into a box

We describe a procedure to compute a projection of `\(w \in ℝ^n\)`

into the intersection of the so-called *zero-norm* ball `\(k B_0\)`

of radius `\(k\)`

, i....

DCISolver.jl: A Julia solver for nonlinear optimization using dynamic control of infeasibility

This paper presents DCISolver.jl a new Julia package implementating the Dynamic Control of Infeasibility method (DCI), introduced by Bielschowsky & Gomes (20...

BibTeX referenceDétection de communautés dynamiques dans les réseaux évolutifs de développeurs au sein de Chrome

The time-stamped database provided by Google traces the code contributions to Chrome browser on the period from September 2008 to January 2014. It describes ...

BibTeX reference

In blackbox optimization, evaluation of the objective and constraint functions is time consuming. In some situations, constraint values may be evaluated in...

BibTeX referenceA derivative-free approach to optimal control problems with a piecewise constant Mayer cost function

A piecewise constant Mayer cost function is used to model optimal control problems in which the state space is partitioned into several regions, each having ...

BibTeX reference

We introduce an iterative method named GPMR for solving 2X2 block unsymmetric linear systems. GPMR is based on a new process that reduces simultaneously...

BibTeX reference

This paper presents an efficient method for extracting the second-order sensitivities from a system of implicit nonlinear equations. We design a custom aut...
