Events

Marion Technical Writer January 28, 2026

Hexaly is delighted to be the sponsor of the 2026 INFORMS Optimization Society Conference (IOS). The event will take place at the Ritz-Carlton, Atlanta, Georgia, USA, from March 20 to 22, 2026. The INFORMS Optimization Society Conference program is available for access here.

Meet Fred Gardi, founder & CEO of Hexaly, and discover the new release, Hexaly 14.5, and its dramatic performance improvements for solving Routing, Scheduling, Packing, and many other problems in Supply Chain and Workforce Optimization. Below are the abstracts of Fred’s talks at the 2026 IOS conference.

Hexaly, Hybrid Optimization Solver, byFred Gardi, Founder & CEO

Hexaly is an innovative hybrid 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 American Operations Research community at the 2026 INFORMS Optimization Society Conference (IOS) in Atlanta.
