What I taught this winter ...

... and last fall

Everybody who is incapable of learning
has taken to teaching.

Oscar Wilde (1854 -- 1900)
The Decay of Lying , p.3


My research

My initial research interests were in graph theory (with an emphasis on hamiltonian cycles and later on perfect graphs) and in combinatorics (with an emphasis on extremal problems and on random discrete structures). Then they extended to analysis of algorithms (with an emphasis on cutting-plane proofs) and to operations research (with an emphasis on linear programming). Through the 1990s, I was preoccupied by the traveling salesman problem.

With my friend Najiba Sbihi, I organized a Séminaire de Mathématiques Supérieures / NATO Advanced Study Institute Combinatorial Optimization: Methods and Applications which took place on 19 -- 30 June 2006 in Montreal. On my own, I organized a workshop Hybrid methods and branching rules in combinatorial optimization, which took place on 18 -- 22 September 2006 in Montreal.

At the end of September 2006, I launched

research laboratory. In the summer of 2009, a group of my friends and I began learning more about predicting epileptic seizures from EEG recordings. I also have a passive interest in computational neuroscience.

Right now I am most interested in two different subjects: the possibility of generalizing the geometrical De Bruijn-Erdős theorem to finite metric spaces and the hope of simulating pseudorandom number generators by McCulloch-Pitts neural nerworks.

Here is my
