Less Is More - On the Importance of Sparsification for Transformers and Graph Neural Networks for TSP

no code implementations25 Mar 2024 Attila Lischka, Jiaming Wu, Rafael Basso, Morteza Haghir Chehreghani, Balázs Kulcsár

Furthermore, we propose ensembles of different sparsification levels allowing models to focus on the most promising parts while also allowing information flow between all nodes of a TSP instance.

Traveling Salesman Problem

Integrated Charging Scheduling and Operational Control for an Electric Bus Network

no code implementations1 Sep 2023 Rémi Lacombe, Nikolce Murgovski, Sébastien Gros, Balázs Kulcsár

We propose a hierarchical control framework to solve this problem, where the charging and operational decisions are taken jointly by solving a mixed-integer linear program in the high-level control layer.

Controlled Descent Training

no code implementations16 Mar 2023 Viktor Andersson, Balázs Varga, Vincent Szolnoky, Andreas Syrén, Rebecka Jörnsten, Balázs Kulcsár

Dynamic label augmentation is proposed within the framework of gradient descent training where the convergence of training loss is controlled.

Conflict-free Charging and Real-time Control for an Electric Bus Network

no code implementations13 Oct 2022 Rémi Lacombe, Nikolce Murgovski, Sébastien Gros, Balázs Kulcsár

The rapid adoption of electric buses by transit agencies around the world is leading to new challenges in the planning and operation of bus networks.

A Predictive Chance Constraint Rebalancing Approach to Mobility-on-Demand Services

no code implementations7 Sep 2022 Sten Elling Tingstad Jacobsen, Anders Lindman, Balázs Kulcsár

We then formulate a SMPC for the autonomous ride-hailing service and integrate demand predictions with uncertainty bounds into a receding horizon MoD optimization.

Parameter and density estimation from real-world traffic data: A kinetic compartmental approach

no code implementations27 Jan 2021 Mike Pereira, Pinar Boyraz Baykas, Balázs Kulcsár, Annika Lang

This system is formulated as a chemical reaction network where road cells are interpreted as compartments, the transfer of vehicles from one cell to the other is seen as a chemical reaction between adjacent compartment and the density of vehicles is seen as a concentration of reactant.
