r19768 - in /trunk: pipe_control/minimise.py specific_analyses/api_base.py specific_analyses/setup.py -- May 29, 2013 - 14:28

Author: bugman
Date: Wed May 29 14:28:48 2013
New Revision: 19768

URL: http://svn.gna.org/viewcvs/relax?rev=19768&view=rev
Log:
Added the ability for specific analyses to override the optimisation 
constraint algorithm.

The default is still the 'Method of Multipliers', but if the 
constraint_algorithm() method returns
a different string, then that will be used to select the algorithm.  This 
allows the 'Log Barrier'
method in minfx to be used.
