BARON is a computational system for solving nonconvex optimization problems to global optimality. Purely continuous, purely integer, and mixed-integer nonlinear problems can be solved with the software. BARON is available under the AIMMS and GAMS modeling languages on a variety of platforms. The GAMS/BARON solver is also available on the NEOS Server.

Baron is a title of honour, often hereditary, and ranks as one of the lower titles in the various nobiliary systems of Europe. The female equivalent is Baroness.
