2026 APDIO Workshop Braga, Portugal

Events

Marion Technical Writer February 16, 2026

Hexaly is pleased to participate in the APDIO 2026 Workshop on Optimization Software Practice. The workshop will take place on March 27, 2026, at the University of Minho, Campus of Gualtar, in Braga, Portugal. You can access the workshop program here or view the event details in the brochure above.

Join us during the event to meet Julien Darlay, Co-Founder & Head of Science at Hexaly, 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 Julien’s talk at the 2026 APDIO Workshop in Braga:

Hexaly, Hybrid Optimization Solver, Julien Darlay, Co-Founder & Head of Science, March 27, 2026, 11h45–12h30

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 Portuguese Operations Research community at the 2026 APDIO Workshop.
