Events

Marion Technical Writer March 6, 2026

Hexaly is delighted to be the Platinum Sponsor of INOC 2026, the conference of the European Network Optimization Group (ENOG). The event will take place from April 22 to 24, 2026, at HEC Liège, Management School of Liège University, Liège, Belgium. You can access the conference program here.

Come visit the Hexaly booth to meet our optimization scientists and explore our new release, Hexaly 14.5, featuring major performance improvements in Routing, Scheduling, and Packing, along with a significant boost in Nonlinear Optimization capabilities. This is also the opportunity to explore and discuss job opportunities at Hexaly. Below is the abstract of Hexaly’s talk at the 2026 INOC conference.

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

Thursday, April 23, 2:30 p.m.

Hexaly is an innovative global optimization solver based on a nonlinear, set-based modeling formalism. This formalism unifies and extends modeling paradigms from mixed-integer linear programming, nonlinear programming, constraint programming, and black-box optimization. Internally, Hexaly integrates a broad range of exact and heuristic optimization techniques, including branch-and-bound, column and cut generation, constraint propagation, and local search, among others. From a computational standpoint, Hexaly demonstrates competitive performance with state-of-the-art solvers such as Gurobi, CPLEX, and OR-Tools, delivering efficient and scalable solutions to routing, scheduling, packing, clustering, and location problems. This presentation introduces the so-called set-based modeling formalism and demonstrates its scalability for solving large-scale problems. It further examines how the solver exploits this formalism to automatically orchestrate advanced exact and heuristic solution methods drawn from the current state of the art.

We look forward to connecting with the Operations Research community at the 2026 INOC conference in Liège, Belgium.
