Dynamic 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...

In this paper we consider an interactive communication system with two users, who sequentially observe two correlated sources, and send the quantized observa...

An augmented Lagrangian (AL) can convert a constrained optimization problem into a sequence of simpler (e.g., unconstrained) problems, which are then usual...

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,...
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...

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...
BibTeX reference
In this paper, we introduce a general framework for vector space decompositions that decompose the set partitioning problem into a reduced problem, defined...
BibTeX reference
Inspired by successful biological collective decision mechanisms such as honey bees searching for a new colony or the collective navigation of fish schoo...
BibTeX reference
We consider a linear-state dynamic game played over an event tree and determine analytically the price of anarchy (PoA), as well as lower and upper bounds ...
BibTeX referenceStrategic support of node-consistent cooperative outcomes in dynamic games played over event trees
In this paper, we show that cooperative outcomes in a dynamic game played over an event tree can be supported strategically, that is, to be part of a subga...

We use a newly developed model of the entire Canadian energy system (TIMES-Canada) to assess the climate change mitigation potential of different agri-food c...

The vehicle routing problem with time windows (VRPTW) consists of finding least-cost vehicle routes to satisfy the demands of customers that can be visited...
BibTeX reference
The subdifferential of a function is a generalization for nonsmooth functions of the concept of gradient. It is frequently used in variational analysis, part...
BibTeX reference
Inventory routing problems aim at minimizing the cost of the total distance traveled over a time horizon discretized in periods, while guaranteeing that th...
