License

BARON.jl is licensed under the MIT License.

The underlying solver is a closed-source commercial product for which you must obtain a license from The Optimization Firm, although a small trial version is available for free.

Installation

First, download a copy of the BARON solver and unpack the executable in a location of your choosing.

Once installed, set the BARON_EXEC environment variable pointing to the BARON executable (full path, including file name as it differs across platforms), and run Pkg.add("BARON"). For example:

ENV["BARON_EXEC"] = "/path/to/baron.exe"
using Pkg
Pkg.add("BARON")

The baronlice.txt license file should be placed in the same directory as the BARON executable, or in your current working directory.
