Is there a way to obtain a free BARON or Knitro license? I am doing academic research and I really need these global optimization solvers (Knitro is not necessarily for global optimization, although it is pretty strong in many problems in global optimization)...
You can use BARON and Knitro for free from the NEOS Server. Also, you have the following options:
- If you are in the first year of graduation, you can apply for a one-year free graduate student license of AMPL which includes both solvers.
- If you are an individual with a CMU or UIUC email address or related to sponsors of the CAPD you can have a free academic license.
You can also download our Octeract Engine - it's free for personal non-commercial use and it solves a superset of the problem types that BARON and KNITRO do (global optimality for non convex problems + trigonometric & nonsmooth & discontinuous problems).
The only limitation is that you'll need to download the newest version every 30 days while the engine is in beta.
