Best Complete MINLP Solver   

BARON is a powerful mathematical optimization software that uses a branch-and-reduce algorithm to automatically generate the best solution for your most difficult optimization 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.         

Solves All Major Optimization Problems

     ✓ Linear programming (LP)       ✓ Mixed-integer programming (MIP)   ✓ Non-linear programming (NLP) Convex and nonconvex     ✓ Mixed-integer nonlinear programming (MINLP) Convex and nonconvex         


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:   

MATLAB  JuMP Pyomo (Python) YALMIP 
AIMMS (separate licensing) AMPL (separate licensing) GAMS (separate licensing)


The Best Solver for Mixed-Integer Nonlinear Programming 

Benchmarks consistently show that BARON is the fastest and most robust MINLP solver. A 2017 independent study found that BARON was 3-10 times faster than other MINLP solvers and solved between 20% and 300% more problems. A 2021 academic study found that BARON is consistently ahead. In a 2023 study conducted by one of our top competitors, BARON was shown to be the best MINLP solver.   

Advanced Algorithms

  •  Deterministic branch-and-reduce exploiting tight convex relations
