DFOS 2026 Montreal, Canada
Hexaly is delighted to be Sponsor of DFOS 2026. The Third Derivative-Free Optimization Symposium. The event will take place from June 22 to 26, 2026, at the Université de Montréal, André-Aisenstadt Building in the room 6214, Montreal, Canada. You can access the conference program here.
Come visit the Hexaly booth and meet Fred Gardi, Founder & CEO of Hexaly, who will be on-site throughout the day. He will be happy to connect if you have questions, want to learn more about our technology, or are curious about the latest features of Hexaly 14.5. This new version 14.5 brings major performance improvements in routing, scheduling, and packing, along with a significant boost in nonlinear optimization capabilities. It is also a great opportunity to discuss career opportunities at Hexaly in an informal setting. Below is the abstracts of Fred’s talk at the 2026 DFOS conference.
Black-Box Optimization with Hexaly, by Fred Gardi, Founder & CEO
Friday, June 26, 2026 – 3:45 P.M
In black-box optimization problems, the analytical form of the objective function and constraints is unknown, and evaluating new solutions can be costly in terms of time and memory. Hexaly provides a surrogate modeling method for optimizing these problems using radial basis function (RBF) models, which helps to reduce the number of evaluations by carefully selecting the points to evaluate. The algorithm combines exploration and intensification phases to make the most of a limited evaluation budget. Additionally, Hexaly handles both analytical and black-box constraints commonly found in industrial applications and can optimize multiple black-box objectives simultaneously. This presentation presents the approach implemented in Hexaly and illustrates its e!ectiveness in real-world applications.
We look forward to connecting with the Canadian Operations Research community at the 2026 DFOS conference in Montreal, Canada.
