Best Complete MINLP Solver

BARON is a global optimization solver that uses a branch-and-reduce algorithm to solve MINLP problems. Our worldwide developers have, on average, doubled MINLP performance with each major BARON release over the last 20 years. BARON is recognized as the best global optimization software available and is a key product used by Fortune 500 companies, national research labs, universities, and more. Learn more about BARON in our Company Brochure.

Innovation

BARON was the first commercial optimization software to solve nonlinear and mixed-integer nonlinear problems with deterministic guarantee. The theory and algorithms implemented in the BARON software are the product of nearly 30 years of academic research recognized by the INFORMS Computing Society Prize and the Beale-Orchard-Hays Prize for excellence in computational mathematical programming.

Support for All Major Interfaces

BARON’s developer-oriented modeling language allows the user to facilitate custom applications through various modeling systems, including:

Why BARON?

The Best Solver for NLP and MINLP  

Benchmarks consistently show that BARON is the fastest and most robust MINLP solver. A 2017 independent study found that BARON was 3-10x faster than other MINLP solvers and solved between 20%-300% more problems. A 2021 academic study found that BARON is consistently ahead. A top competitor conducted a 2023 study that showed BARON is the best MINLP solver.
