Penalties and Rewards for Fair Learning in Paired Kidney Exchange Programs
Margarida Carvalho, Alison Caulfield, Yi Lin +1
A kidney exchange program, also called a kidney paired donation program, can be viewed as a repeated, dynamic trading and allocation mechanism. This suggests that a dynamic algorit…
Integer Programming Games: A Gentle Computational Overview
Margarida Carvalho, Gabriele Dragotto, Andrea Lodi +1
In this tutorial, we present a computational overview on computing Nash equilibria in Integer Programming Games (s), , how to compute solutions for a class of non-cooper…
Asymmetry in the Complexity of the Multi-Commodity Network Pricing Problem
Quang Minh Bui, Margarida Carvalho, José Neto
The network pricing problem (NPP) is a bilevel problem, where the leader optimizes its revenue by deciding on the prices of certain arcs in a graph, while expecting the followers (…
A stochastic integer programming approach to reserve staff scheduling with preferences
Carl Perreault-Lafleur, Margarida Carvalho, Guy Desaulniers
Nowadays, reaching a high level of employee satisfaction in efficient schedules is an important and difficult task faced by companies. We tackle a new variant of the personnel sche…
Adaptation, Comparison and Practical Implementation of Fairness Schemes in Kidney Exchange Programs
William St-Arnaud, Margarida Carvalho, Golnoosh Farnadi
In Kidney Exchange Programs (KEPs), each participating patient is registered together with an incompatible donor. Donors without an incompatible patient can also register. Then, KE…
Optimising Electric Vehicle Charging Station Placement using Advanced Discrete Choice Models
Steven Lamontagne, Margarida Carvalho, Emma Frejinger +3
We present a new model for finding the optimal placement of electric vehicle charging stations across a multi-period time frame so as to maximise electric vehicle adoption. Via the…
The Cut-and-Play Algorithm: Computing Nash Equilibria via Outer Approximations
Margarida Carvalho, Gabriele Dragotto, Andrea Lodi +1
We introduce Cut-and-Play, a practically-efficient algorithm for computing Nash equilibria in simultaneous non-cooperative games where players decide via nonconvex and possibly unb…
A Catalog of Formulations for the Network Pricing Problem
Quang Minh Bui, Bernard Gendron, Margarida Carvalho
We study the network pricing problem where the leader maximizes their revenue by determining the optimal amounts of tolls to charge on a set of arcs, under the assumption that the…
