What is it about?

The development of derivative-free optimization has been forced by the need to optimize various and often increasingly complex problems in practice. A new DIRECTGO MATLAB toolbox entitles solutions to derivative-free box-constrained, generally-constrained, and problems with hidden constraints.

Why is it important?

Recent reviews and comparisons revealed that, on average, DIRECT-type algorithms performance is one of the best among all tested state-of-the-art derivative-free global optimization approaches. Open Source Software (DIRECTGO) enables everyone, i.e., practitioners and the scientific community, to use the most efficient DIRECT-type algorithms and contribute to their further development.


This paper summarises a decade of work on the DIRECT topic and opens open-source software to the broader optimization community.
