| 16:40 on Feb 23 | minfx | Commit by bugman :: r68 /trunk/minfx/grid.py: Fix for grid_split() for when the number of divisions is more than the total number of points.
The last divisions are discarded in this case. | # | | 21:40 on Feb 22 | minfx | Commit by bugman :: r67 /trunk/minfx/grid.py: Added the function grid_point_array() for finding the minimum point in an array of grid points.
This allows for completely non-linear grid searches as each point is arbitrary. | # | | 21:16 on Feb 22 | minfx | Commit by bugman :: r66 /trunk/minfx/grid.py: Added support for constraints into grid_split().
Points which violate the constraints are now eliminated prior to the grid subdivision. | # | | 21:04 on Feb 22 | minfx | Commit by bugman :: r65 /trunk/minfx/grid.py: Added the grid_split() generator function.
This takes a linear gird, converts it to a linear array of points, and then splits these returning each grid subdivision. | # | | 18:07 on Oct 07, 2009 | minfx | Commit by bugman :: r64 /trunk/minfx/ (base_classes.py grid.py): The optimisation output is more consistent.
The numpy array has been even better formatted. | # | | 16:18 on Sep 22, 2009 | minfx | Commit by bugman :: r63 /trunk/minfx/generic.py: Bug fix for the catching of models with zero parameters. | # | | 16:17 on Sep 22, 2009 | minfx | Commit by bugman :: r62 /trunk/minfx/grid.py: Modified the grid search to return a warning and to handle models with zero parameters. | # | | 18:34 on Sep 21, 2009 | minfx | Commit by bugman :: r61 /trunk/minfx/generic.py: The output of generic_minimise() has been cleaned up - the numpy parameter is printed as a list. | # | | 18:33 on Sep 21, 2009 | minfx | Commit by bugman :: r60 /trunk/minfx/base_classes.py: The optimisation output has been prettified - the numpy array has been better formatted. | # | | 18:13 on Sep 21, 2009 | minfx | Commit by bugman :: r59 /trunk/minfx/grid.py: Removed some debugging code. | # | | 18:11 on Sep 21, 2009 | minfx | Commit by bugman :: r58 /trunk/minfx/grid.py: Modified the grid search print out to be prettier. | # | | 18:00 on Sep 21, 2009 | minfx | Commit by bugman :: r57 /trunk/minfx/grid.py: Redesigned the grid search function.
The grid_ops arg has been replaced by the more intuitive num_incs, lower and upper args fro the number of increments, lower bound, and upper bound value lists respectively.
The new incs argument has been added to allow custom non-linear grid searches.
The new MinfxError system is now being used, and many arguments are being checked.
The docstring has been converted to epydoc format. | # | | 13:25 on Sep 21, 2009 | minfx | Commit by bugman :: r56 /trunk/minfx/generic.py: A MinfxError is now raised if the supplied minimisation algorithm cannot be identified. | # | | 13:25 on Sep 21, 2009 | minfx | Commit by bugman :: r55 /trunk/minfx/errors.py: Added a rudimentary error system. | # | | 12:41 on Sep 21, 2009 | minfx | Commit by bugman :: r54 /trunk/minfx/generic.py: Removed the grid search option from the generic_minimise() function.
The minimisation options are too messy and inflexible. The grid search should be preformed by direct calls to grid.grid(). | # | | 12:32 on Sep 21, 2009 | minfx | Commit by bugman :: r53 /trunk/minfx/grid.py: Modified the grid search print out to indicated the number of grid points used. | # | | 13:32 on Jul 30, 2009 | minfx | Commit by bugman :: r52 /trunk/doc/Release_Checklist: Some more fixes for the release checklist document. | # | | 13:09 on Jul 30, 2009 | minfx | Commit by bugman :: r51 /tags/1.0.2/setup.py: Updated the version number to 1.0.2. | # | | 13:08 on Jul 30, 2009 | minfx | Commit by bugman :: r50 /trunk/CHANGES: | # | | 13:07 on Jul 30, 2009 | minfx | Commit by bugman :: r49 /trunk/doc/Release_Checklist: Fix for the release checklist document. | # |
