ALADIN-α—An open-source MATLAB toolbox for distributed non-convex optimization

Abstract

This article introduces an open-source software for distributed and decentralized non-convex optimization named ALADIN- (Formula presented.). ALADIN- (Formula presented.) is a MATLAB implementation of tailored variants of the Augmented Lagrangian Alternating Direction Inexact Newton (ALADIN) algorithm. It is user interface is convenient for rapid prototyping of non-convex distributed optimization algorithms. An improved version of the recently proposed bi-level variant of ALADIN is included enabling decentralized non-convex optimization with reduced information exchange. A collection of examples from different applications fields including chemical engineering, robotics, and power systems underpins the potential of ALADIN- (Formula presented.).
