Détection 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 ...

In blackbox optimization, evaluation of the objective and constraint functions is time consuming. In some situations, constraint values may be evaluated in...
BibTeX reference
In this paper, we study a distributionally robust multi-item newsvendor problem, where the demand distribution is unknown but specified with a general event-...
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 ...

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...

For a simple connected graph G
, let D(G), Tr(G)
, DL(G)=Tr(G)−D(G)
, and DQ(G)=Tr(G)+D(G)
be the distance matrix, the diagonal m...
A small polygon is a polygon of unit diameter. The maximal area of a small polygon with n=2m
vertices is not known when m≥7
. In this paper, w...
The Tenth Montreal IPSW took place on August 13-27, 2020, and was jointly organized by the Centre de recherches mathématiques (CRM) and the Institute for Dat...

For a graph G
, the signless Laplacian matrix Q(G)
defined as Q(G)=D(G)+A(G)
, where A(G)
is the adjacency matrix of G
and `...
This paper studies a stochastic variant of the vehicle routing problem (VRP) where both customer locations and demands are uncertain. In particular, potentia...
BibTeX reference
This paper introduces the consistent production routing problem in a setting with multiple plants and products. The problem consists in finding minimum-cost ...

We propose a tone-based event study to reveal the aggregate abnormal tone dynamics in media articles around earnings announcements. We test whether they co...
BibTeX reference
We study bin-packing and lot-sizing decisions in an integrated way. Such a problem appears in several manufacturing settings where items first need to be cu...

In this paper we examine the stability of international environmental agreements about a (common) emissions target. By signing the agreement, the parties d...
BibTeX reference
The increasingly complex energy systems are turning the attention towards model-free control approaches such as reinforcement learning (RL). This work propos...

A small polygon is a polygon of unit diameter. The maximal width of an equilateral small polygon with n=2s
vertices is not known when s≥3
. T...
Robust integration of electric vehicles charging load in smart grids capacity expansion planning
Battery charging of electric vehicles (EVs) needs to be properly coordinated by electricity producers to maintain the network reliability. In this paper, we ...
