2025 INFORMS Analytics+ Conference
Hexaly is the Platinum sponsor of the 2025 INFORMS Analytics+ Conference, April 6-8, 2025, at the JW Marriott Indianapolis, Indiana, USA.
Come by the Hexaly booth to meet Fred Gardi, Founder & CEO of Hexaly, and discover the new release Hexaly 13.5, which delivers dramatic performance improvements for solving Routing, Scheduling, Packing, Clustering, Assignment, Location, and many other problems in Supply Chain and Workforce Optimization. This is also the opportunity to explore and discuss our many job offers. Below are the abstracts of Fred’s talks at the 2025 INFORMS Analytics+ Conference.
Hexaly Exhibitor Workshop, Sunday, April 6, 2025, 3-4:45 pm: “Hexaly, a new kind of global optimization solver” by Fred Gardi, Ph.D., founder & CEO
Hexaly is a new type of global optimization solver. Its modeling interface is nonlinear and set-oriented. It also supports user-coded functions, enabling seamless integration of simulation with optimization or machine learning with optimization. The Hexaly API unifies modeling concepts from mixed-integer programming, nonlinear programming, and constraint programming. Under the hood, Hexaly combines various exact and heuristic optimization methods: spatial branch-and-bound, simplex methods, interior-point methods, propagation, automatic branch-cut-price, local search, and surrogate modeling.
Hexaly stands out from traditional solvers like Gurobi, CPLEX, and OR-Tools by delivering super-fast solutions to problems such as routing, sequencing, scheduling, packing, clustering, matching, assignment, and location. For example, Hexaly provides solutions close to the best-known results in the literature for vehicle routing problems with thousands of points and scheduling problems with millions of tasks, achieving this in just one minute of runtime on a basic computer.
In addition to the Optimizer, Hexaly offers an innovative platform called Hexaly Studio, designed to prototype, develop, and deploy optimization applications quickly in a low-code fashion. This web-based platform is also well-suited for educational purposes; like all other Hexaly products, it is free for faculty and students.
Hexaly Technology Workshop, Monday, April 7, 3:40-4:30 pm: “Automatic Branch-Cut-Price in Hexaly” by Fred Gardi, Ph.D., founder & CEO
Hexaly is a new kind of global optimization solver. Its modeling interface is nonlinear and set-oriented. It also supports user-coded functions, enabling seamless integration of simulation with optimization or machine learning with optimization. The Hexaly API unifies modeling concepts from mixed-integer linear programming, nonlinear programming, and constraint programming. Under the hood, Hexaly combines various exact and heuristic optimization methods to solve users’ problems effectively.
In this talk, we will explain how Hexaly leverages Branch-Cut-Price techniques to automatically solve vehicle routing problems with hundreds of points, achieving near-optimal solutions within minutes on a standard laptop. Here, “automatically” means out-of-the-box: no additional information or parameter tuning is required from the user.
