Hexaly is delighted to be the platinum sponsor of MIP Workshop South America 2025. The event will occur at Universidad Adolfo Ibáñez in Viña del Mar, Chile on December 9-12, 2025. The 2025 MIP Workshop program can be accessed here.

Come meet   Fred Gardi, Founder & CEO of Hexaly, and discover the new release Hexaly 14.0 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 2025 MIP Workshop South America .

Hexaly: a super-fast, super-scalable optimization solver, by Fred Gardi, founder & CEO

Hexaly is a new type of 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 MILP and CP solvers by delivering super-fast solutions to very large-scale problems like routing, scheduling, sequencing, 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.

We look forward to connecting with the operations research community at MIP Workshop South America 2025.
