ROUTE 2026 Kongens Lyngby, Denmark

Events

Marion Technical Writer May 11, 2026

Hexaly is delighted to be the Gold Sponsor of ROUTE 2026. The event aims to provide a forum for scientific exchange and cooperation in vehicle routing, intermodal transportation, and related fields. The event will take place from Sunday, May 31, to Wednesday, June 3, 2026, at the Frederiksdal Conference Center in Kongens Lyngby, Denmark. You can access the conference program here.

Come visit the Hexaly booth and meet our Optimization Scientist, Lorenzo Canonne, Ph.D., 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 abstract of Hexaly’s talk at the 2026 ROUTE conference.

Hexaly, a new kind of global optimization solver, by Lorenzo Canonne, Ph.D.
Monday, June 1st 2026, 9:30 AM

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 from leading solvers such as Gurobi, IBM Cplex, and Google OR Tools by delivering fast, scalable solutions for 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 Danish Operations Research community at the 2026 ROUTE conference in Kongens Lyngby, Denmark.
