Our paper A survey of nonlinear robust optimization (Sven Leyffer, Matt Menickelly, Todd Munson, Charlie Vanaret and Stefan M. Wild) was published online today in the INFOR: Information Systems and Operational Research journal.
Our preprint Two-phase approaches to optimal model-based design of experiments: how many experiments and which ones? is online on ResearchGate!
On the occasion of the 5th anniversary of my doctoral defense in Toulouse (France), I finally completed the English translation of my dissertation, entitled “Hybridization of interval methods and evolutionary algorithms for solving difficult optimization problems“.
My rigorous solver Charibde combines an interval branch and contract algorithm with an evolutionary algorithm in a parallel fashion ; the two algorithms exchange bounds, solutions and domains via message passing, in order to intensify the pruning of the search space. Charibde proved competitive with interval-based solvers GlobSol, IBBA and Ibex on a subset of difficult COCONUT problems. I also provided new optimality results for highly multimodal problems for which few (even approximate) solutions are known. Finally, I presented the first numerical proof of optimality for the open Lennard-Jones problem with five atoms. State-of-the-art interval-based solvers did not converge within reasonable time, while exhaustive solvers BARON and Couenne produced erroneous results.
I submitted our paper Two-phase approaches to optimal model-based design of experiments: how many experiments and which ones? to Chemical Engineering Science.
It was cowritten with Philipp Seufert, Jan Schwientek, Michael Bortz (Fraunhofer ITWM), Glep Karpov, Gleb Ryzhakov, Ivan Oseledets (Skoltech) and Norbert Asprion (BASF).
Sven Leyffer and I submitted our paper An Augmented Lagrangian Filter Method to the Mathematical Methods of Operations Research (MMOR) journal.
Our survey A Survey of Nonlinear Robust Optimization was accepted for publication in the INFOR: Information Systems and Operational Research journal.
