Version 3.1.0 |
|
-
The documentation/help has had a complete overhaul including:
-
A completely new presentation interface (Sphinx).
-
Proof reading!
-
Updating for latest features.
-
A Help (or sometimes ?) button has been added to every panel, and some sub panels if appropriate, linking to the appropriate section in the documentation.
-
The model help has been split so that the Details button now brings up a very short pop-up giving the equation being used while HELP goes to the section in the full documentation describing the model.
-
Extensive help has also been added for the new optimizer engine (see below) including rules of thumb on how and when to choose a given optimizer and what the parameters do.
-
The optimizer engine has been completely replaced. The new optimizer still defaults to the standard Levenberg-Marquardt algorithm. However 4 other optimizers are now also available. Each starts with a set of default parameters which can be tuned. The DREAM optimizer takes the longest but is the most powerful and yields rich information including full parameter correlation and uncertainty plots. A results panel has been added to accommodate this.
-
The five new optimizers are:
- A Levenberg-Marquardt optimizer
- A Quasi-Newton BFGS optimizer
- A Nelder-Mead Simplex optimizer
- A Differential Evolution optimizer
- A Monte Carlo optimizer (DREAM)
-
New models were added:
- MicelleSphCoreModel (currently residing in the Uncategorized category)
-
Existing models were updated:
- LamellarPS (bug in polydispersity integration fixed)
- RectangularPrismModel
- RectangularHollowPrismModel
- RectangularHollowPrismInfThinWallsModel
-
A number of bugs were fixed including a thread crashing issue and an incorrect slit smearing resolution calculation.
-
Implemented much more robust error logging to enable much easier debugging in general but particularly the debugging of issues reported by SasView users.
