ALC Augmented Lagrangian Coordination toolbox and PSI specification language

The archive file psi+alc-0.1.3.tar.gz contains the Matlab implementation of the Augmented Lagrangian Coordination method as described in the paper (link):

S. Tosserams, L.F.P. Etman, J.E. Rooda (2008),
Augmented Lagrangian coordination for distributed optimal design in MDO
International Journal for Numerical Methods in Engineering, Vol 73. Issue 13, pp. 1885-1910

and the Python sources of the compiler and generators for the PSI specification language as described in the paper (open access):

S. Tosserams, A.T. Hofkamp, L.F.P. Etman, and J.E. Rooda (2010),
A specification language for problem partitioning in decomposition-based design optimization 
Structural and Multidisciplinary Optimization: Volume 42, Issue 5 (2010), Page 707.
published under open access: DOI 10.1007/s00158-010-0512-z

We appreciate that publications describing work using (part of) this software quote the reference(s) given above.

To run the Matlab files you need the fmincon constrained minimizer from the Matlab optimization toolbox.

The zip file includes documentation.

The Matlab ALC implementation was developed by Simon Tosserams in 2008 (s.tosserams@tue.nl) with Matlab release R14, the Python PSI code was developed by Albert Hofkamp in 2009 (a.t.hofkamp@tue.nl) with Python 2.4 at a Linux platform.
