Henri Lefebvre

I am a CNRS researcher hosted by LIRMM in Montpellier (France). I received my PhD in Operations Research from the University of Bologna in 2023, under the supervision of Michele Monaci and Enrico Malaguti. My doctoral research focused on optimization problems under uncertainty, with a particular emphasis on robust optimization. In 2024, I was awarded the EURO Best Dissertation Award by the Association of European Operational Research Societies. I then worked as a postdoctoral researcher at the University of Trier (Germany) in the working group of Martin Schmidt.

My research focuses on the development of algorithms for complex decision-making problems involving uncertainty and multiple decision-makers. I aim to design generic approaches applicable to broad classes of problems, which can be adapted to specific real-world scenarios.

Meet idol: a C++ Framework for Optimization!

idol is a framework designed to help solve complex optimization problems using a variety of decomposition methods. It enables the development of custom algorithms for mixed-integer, robust, and bilevel optimization problems. 

const auto branch_and_price = branch_and_bound + column_generation;
model.use(branch_and_price);
model.optimize();
