Combinatorics, Optimization and Algorithms for Telecommunications

Team presentation

COATI's main objective is to develop algorithmic methods and tools, with particular emphasis on the design and operation of telecommunication networks, and algorithm design for transportation networks. This involves high level research in the fields of combinatorial optimization, algorithms, and discrete mathematics.

Research themes

  • Algorithms, discrete mathematics and combinatorial optimization.
  • Graph Theory.
  • Networks design and management (SDN, NFV, 5G, optical WDM, MPLS, Backhaul, LTE, etc.).
  • Transportation networks

International and industrial relations

  • Industrial partnerships
    • Instant-System: (ANR MULTIMOD) algorithms for fast computation of personalized itineraries in large-scale public multimodal transportation networks.
    • Benomad: (ANR MULTIMOD) routing algorithms in road networks.
    • Orange labs: contract CIFRE (2018–2021) with project team DIANA.
    • Pôle de Compétitivité SCS
