VEROLOG 2026 Bath, United Kingdom

Events

Marion Technical Writer May 27, 2026

Hexaly is delighted to be the Sponsor of VEROLOG 2026,  the 10th annual meeting of the EURO working group on Vehicle Routing and Logistics optimization (VeRoLog). The event will take place from July 6 to 9, 2026, at University of Bath, Bath,United Kingdom. You can access the conference program here.

Come visit the Hexaly booth and meet Maxime Rougier, Optimization Scientist at 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 abstract of Hexaly’s talk at the 2026 VEROLOG conference.

Hexaly, a new kind of global optimization solver, by Maxime Rougier, Optimization scientist

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 Operations Research community at the 2026 VEROLOG conference in Bath, United Kingdom.
