Organizing the Derivative-free and Simulation-based Optimization Stream @ISMP 2024!
I am one of the organizers of the Derivative-free and Simulation-based Optimization Stream @ISMP 2024.
ISMP is a triennial conference on mathematical optimization, gathering scientists from around the world to present and share their most recent advances and development in the field. It is also a unique opportunity to discuss new challenges and opportunities in practice and theory of mathematical optimization.
ISMP 2024 will be held in Montréal, Canada, from July 21st through July 26th, 2024.
Check the details here.

DFOS 24 @ UNIPD!
The 2nd Derivative-free Optimization Symposium (DFOS) will be held from Monday, June 24th to Friday, June 28th, 2024 at the University of Padova, Padova, Italy.
This is a single-track symposium, highlighting the latest trends in Derivative-free Optimization (DFO), with invited speakers only. The main goal is to find new connections between research focused in DFO algorithmic design and novel applications of DFO. A single-track workshop facilitates the interaction among participants, strengthening possibilities of collaboration.
