publications policy — I do my best to maintain updated versions with possible typo corrections and clarifications on arxiv (both are generally marked in bold and red for easy reference). Therefore, please favor the arxiv versions to the official published ones.

thesis — my thesis (under the supervision of François Glineur and Julien Hendrickx) had the chance to be awarded the ICTEAM thesis award for 2018, the IBM-FNRS innovation award for 2018, and to be a finalist for the AW Tucker prize for 2018. In addition, we received the 2017 best paper award in Optimization Letters, for a joint work with Etienne de Klerk and François Glineur (for this paper).

codes — see my github profile for all my codes. The current version of the Performance EStimation TOolbox (PESTO) is available from here (user manual, conference proceeding). The numerical worst-case analyses from PEP can now be performed just by writting the algorithms just as you would implement them in Matlab. The new PEPit (performance estimation in Python) is available from here (due to the fabulous work of Baptiste Goujaud and Céline Moucer). It is easy to experiment with it using this notebook (see colab).
