PhytoSim Calibration Change Log

Version 1.2.2

Fixes
  • Fixed a problem with missing Data I/O data when starting a calibration.

Version 1.2.1

Fixes
  • Fixed GUI slow-down when plotting many infinite objective values on the 'Objective Value vs. Evaluation Number' graph.

Version 1.2

New features
  • Confidence information calculations: estimation errors and correlation matrix.
  • Added the 'Single shot' optimizer: evaluate the objective at the initial values.
  • Zooming is now allowed on all graphs.
  • 'Best' simulation curve now has a +/- 2*stdev measurement uncertainty band on it.
  • Minimum and maximum graph marker lines for optimizer variables.
  • New example: HydR, linking diameter changes to radial water transport across a radial hydraulic resistance (Steppe et al., 2011). Only available for non-trial accounts.

Version 1.1

New features
  • Added tooltips for the optimizer variable types.
Changes
  • Changed to standard deviation of y in the Linear calibration example to 0.5.
Fixes
  • Fixed title of the 'To simulation' dialog box.
  • Added a bounds check for the optimizer variable initial values.
  • Simulations that terminate prematurely don't count when calculating the objective value.

Version 1.0

Fixes
  • Better error messages when input data has been removed.
  • Problem with copying best values to the simulation.
  • Problem with 'ghost' optimizer and objective variables (caused when removing a model component that was used in a calibration).

Version 0.5.1

Fixes
  • Unit conversion problem when changing an input independent variable unit.
  • External data simulation curve F_stem_data did not point to the correct data input column.

Version 0.5

New features
  • Unit support.
Changes
  • The simulation start and stop values determine which part of the calibration data is shown.
Fixes
  • Objective graph curve labels are updated when a model component name changes.

Version 0.4

New features
  • Model support for exponential integrals.

Version 0.3

New features
  • New example: RCGro2, water transport and storage model (De Pauw et al., 2008).
  • New example: Staci, model of the Software Tool for Automatic Control of Irrigation (Steppe et al., 2008).
  • New example: ZweifelPotentialTranspiration (Zweifel et al., 2002), calibration using a custom objective for a 30-day data set of an oak tree.

Version 0.2

New features
  • User guide.
Fixes
  • Rescaling issue on objective graph for multiple objective variable contributions.

Version 0.1

New features
  • Initial module release.
  • Examples are in the PhytoSim/Examples/PhytoSimCalibration folder.
