ALADIN-alpha

ALADIN-alpha is a rapid-prototyping toolbox for distributed and decentralized non-convex optimization. ALADIN-alpha implements the Augmented Lagrangian Alternating Direction Inexact Newton (ALADIN) algorithm and the Alternating Direction of Multipliers Method (ADMM) with a unified interface. Moreover, bi-level ALADIN is included in ALADIN-alpha allowing for decentralized non-convex optimization. Application examples from various fields highlight the broad applicability of ALADIN-alpha. A documentation can be found here.

Getting started

1. Download ALADIN-M and add the \src folder including all subfolders folder to you MATLAB path.
2. Run \exampels\main_example.m.

Highlights
