Marion Technical Writer October 22, 2025

Hexaly is delighted to be the gold sponsor of OPTIMA 2025 in Coquimbo, Chile. The event will take place at Universidad Católica del Norte (UCN), Guayacán Campus, from December 1 to 3, 2025. The OPTIMA 2025 program can be accessed here.

Come by the Hexaly booth at OPTIMA 2025 in Coquimbo to 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 is the abstract of Fred’s talks at the OPTIMA 2025 conference.

We look forward to connecting with the Chilean Operations Research community at OPTIMA 2025 in Coquimbo, Chile.

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 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, such as 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.
