DESCRIPTION:Wenjie Xu (LA3\, EPFL)\nAbstract:\nOptimizing the performance 
 of unknown black-box systems with unmodeled constraints is a ubiquitous pr
 oblem in science and engineering. In this talk\, I will present the CONFIG
  algorithm\, a simple and provably efficient constrained global optimizati
 on algorithm to solve it. We also demonstrate the effectiveness of CONFI
 G algorithm in the applications. It is first applied to a set of artificia
 l numerical benchmark problems to corroborate its effectiveness. It is the
 n applied to a classical constrained steady-state optimization problem of 
 a continuous stirred-tank reactor. Simulation results show that our CONFIG
  algorithm can achieve performance competitive with the popular CEI algori
 thm\, which has no known optimality guarantee. As such\, the CONFIG algori
 thm offers a new tool\, with both a global optimality guarantee and compet
 itive empirical performance\, to optimize the performance for a black-box
  system with soft unmodeled constraints. Last\, but not least\, the open-
 source code is available as a python package to facilitate future applicat
 ions.\n\nBiography:\nWenjie Xu is a Ph.D. candidate in Electrical Enginee
 ring with the Automatic Control Laboratory\, EPFL\, and a guest Ph.D. stud
 ent with the Urban Energy Systems Laboratory at Empa. He is jointly super
 vised by Prof. Colin Jones at EPFL and Dr. Bratislav Svetozarevic from Em
 pa. He received MPhil degree from The Chinese University of Hong Kong in 2
 020 and B.E. degree from Tsinghua University in 2018. His research intere
 sts include data-driven optimization\, controller tuning\, intelligent tra
 nsportation\, and smart energy systems\, with research results published 
 in IEEE journals (T-ITS\, T-NNLS)\, ACM conferences (MobiHoc\, BuildSys) 
 and control conferences (ACC\, IFAC). He received the ASME Energy Systems
  Technical Committee Best Paper Award at the 2022 American Control Confere
 nce.
