COAgents: Multi-Agent Framework to Learn and Navigate Routing Problems Search Space

Oleksandr Yakovenko, Mahdi Mostajabdaveh, Cheikh Ahmed +4

Although Vehicle Routing Problems (VRP) are essential to many real-world systems, they remain computationally intractable at scale due to their combinatorial complexity. Traditiona…

Latent Heuristic Search: Continuous Optimization for Automated Algorithm Design

Cheikh Ahmed, Mahdi Mostajabdaveh, Zirui Zhou

The integration of Large Language Models (LLMs) into evolutionary frameworks has established a new paradigm for automated heuristic discovery. Despite their promise, these methods…

Deep Learning for Data-Driven Districting-and-Routing

Arthur Ferraz, Cheikh Ahmed, Quentin Cappart +1

Districting-and-routing is a strategic problem aiming to aggregate basic geographical units (e.g., zip codes) into delivery districts. Its goal is to minimize the expected long-ter…

Discrete Optimization of Min-Max Violation and its Applications Across Computational Sciences

Cheikh Ahmed, Mahdi Mostajabdaveh, Samin Aref +1

We introduce the Discrete Min-Max Violation (DMMV) as a general optimization problem which seeks an assignment of discrete values to variables that minimizes the largest constraint…

DistrictNet: Decision-aware learning for geographical districting

Cheikh Ahmed, Alexandre Forel, Axel Parmentier +1

Districting is a complex combinatorial problem that consists in partitioning a geographical area into small districts. In logistics, it is a major strategic decision determining op…
