IPCO 2026 Padova, Italy
Hexaly is delighted to be the Gold Sponsor of IPCO 2026, the 27th Conference on Integer Programming and Combinatorial Optimization. The event will take place from June 15 to 19, 2026, at the Elettra room at Palazzo della Salute , Padova, Italy. You can access the conference program here.
Come visit the Hexaly booth and meet Thierry Benoist, Founder & CEO of Hexaly, who will be on-site throughout the day. They 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.
Hexaly, a new kind of global optimization solver, by Thierry Benoist, Founder & CEO of Hexaly
Friday, June 19, 2026, 15:30–16:00
Hexaly is a new type of global optimization solver. Its modeling formalism is hybrid, unifying concepts from mixed-integer programming, nonlinear programming, constraint programming, and black-box optimization. As a result, it is nonlinear, set-oriented, and supports user-coded functions, enabling seamless integration of simulation with optimization or machine learning with optimization.
A central design objective is modeling expressiveness and openness: enabling users to formulate problems closer to their natural combinatorial structure, while allowing diverse algorithmic components to interact in a complementary manner.
In this talk, we will present the guiding principles behind this approach, with a particular focus on discrete optimization problems where Hexaly currently demonstrates its strongest performance, such as large‑scale routing, scheduling, and packing. We will also explain how Hexaly combines exact and heuristic optimization methods: spatial branch-and-bound, simplex methods, interior-point methods, constraint propagation, automatic branch-cut-price, local search, surrogate modeling, among others.
We look forward to connecting with the Italian Operations Research community at the 2026 IPCO conference in Padova, Italy.
