Manual and FAQs

Download the BARON User Manual to read about software features, see examples of inputs, and learn how to use BARON executables through BARON’s own parser-reader of optimization models. Please see our BARON FAQ page for more information.

Tutorials

Several BARON tutorials can be found on our YouTube channel, including introductory videos, conference workshop recordings, and more.

Interfaces

You can use BARON executables through BARON's own parser-reader of optimization models. Alternatively, you can access the same executables through the freely available MATLAB/BARON Interface and the JuMP, Pyomo, and YALMIP modeling systems.

BARON Demo

Without a valid BARON license, the system will operate in free demo mode, which allows you to inspect the user interface, edit and run input files, and investigate other design outputs, but it will not handle large problems. The BARON log will indicate that your system runs in demo mode. BARON demo mode handles up to 10 constraints and variables and up to 50 nonlinear operations.

Examples of BARON Input Files

• Nonconvex nonlinear problems: nlp1, nlp2
• Mixed-integer linear problem: milp
• Mixed-integer nonlinear problem: minlp
• Separable concave or indefinite quadratic problems: scqp1, scqp2, iqp
• Miscellaneous applications: pooling, gear design, robot

A Large Collection of Optimization Problems

We provide a large test set of linear programming (LP) and nonlinear programming (NLP) problems.
