CPAIOR 2026 Rabat, Morocco

Events

Marion Technical Writer April 28, 2026

Hexaly is delighted to be the Platinum Sponsor of CPAIOR 2026, The 23rd International Conference on the Integration of Constraint Programming, Artificial Intelligence, and Operations Research. The event will take place from May 26 to 29, 2026, at the ESSEC Business School campus, Rabat, Morocco. You can access the conference program here.

Come visit the Hexaly booth and meet our Optimization Scientist, Francesco Gallo., 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.

Hexaly, a new kind of global optimization solver, by Francesco Gallo

Thursday, 28 May 2026, 4:00 — 5:00 P.M

Hexaly Optimizer is a new kind of global optimization solver. Its modeling interface is nonlinear and set-oriented. In a sense, Hexaly APIs unify and extend modeling concepts from mixed-linear programming, nonlinear programming, constraint programming, and black-box optimization. Under the hood, Hexaly combines various exact and heuristic optimization methods, such as branch-and-bound, automatic Dantzig-Wolfe reformulation, column and row generation, propagation methods, local search, direct search, and surrogate modeling techniques.

Regarding performance benchmarks, Hexaly distinguishes itself against the leading solvers in the market, like Gurobi, IBM Cplex, and Google OR Tools, by delivering fast and scalable solutions to Routing, Scheduling, Packing, Clustering, and Location problems.

This talk will introduce our set-based modeling formalism and show its scalability for large instances. We will then explore how the solver can use this formalism to automatically use state-of-the-art resolution techniques from the exact and heuristic fields.

We look forward to connecting with the African Operations Research community at the 2026 CPAIOR conference in Rabat, Morocco.
