BenchOpt is a package to simplify, make more transparent and more reproducible the comparisons of optimization algorithms. It is written in Python but it is available with many programming languages. So far it has been tested with Python, R, Julia and compiled binaries written in C/C++. available via a terminal command. BenchOpt is used through a command line tools and you can easily add your own solvers. Ultimately the purpose is to be able to run and replicate an optimization benchmark in the most simple and fair way when designing and programming algorithms as well as when reviewing existing methods.
