Feodor-Lynen Postdoctoral Research Fellow Dr. FLORIANE MEFO KUE Lectures Students On Bilevel Optimization Problems and Newton-type Methods

She mounted the podium of the main lecture hall on October 19th, 2021 to give a talk to 9th Cohort students on her research work titled “Bilevel Optimization Problems and Newton-type Methods”

To the attentive audience, Dr. Kue gave several theoretical foundations of bilevel programming problems and introduced them to different reformulations as one-level optimization problems.

Part of Dr. Kue’s research work was dedicated to the study of a bilevel program involving a linear lower level problem with lefthand-side perturbation. She considered the Karush-Kuhn-Tucker reformulation of the problem and subsequently built a tractable optimization problem with linear constraints by means of a partial exact penalization. A semi-smooth system of equations was then generated from the later problem and a Newton-type method was developed to solve it. She illustrated the practical implementation of the algorithm on the optimal toll-setting problem in transportation networks.

Early April 2021, the Alexander von Humboldt Foundation awarded Dr. Kue the prestigious Feodor-Lynen Research Fellowship for a two-year research stay at AIMS Cameroon. Dr. Kue started the fellowship in August 2021 at AIMS Cameroon, with the Centre’s President, Prof. Mama Foupouagnigni as academic host and main research collaborator.

Granted by the Alexander von Humboldt Foundation, with funding from the Federal Ministry of Education and Research, the Feodor-Lynen Fellowship enables researchers from Germany at all career levels and all disciplines to conduct research with members of the Humboldt network around the world.
