Tom M. Ragonneau
Actively developing software for derivative-free optimization.

Self introduction

I am a Ph.D. candidate in the Department of Applied Mathematics at The Hong Kong Polytechnic University, advised by Dr. Zaikun Zhang and Prof. Xiaojun Chen, and supported by the University Grants Committee (UGC) of Hong Kong, under the Hong Kong Ph.D. Fellowship Scheme (HKPFS, ref. PF18-24698).

Research overview

My research interests include mathematical optimization and its applications, especially methods based on inaccurate information and methods dedicated to derivative-free optimization.
