Analytica 5.2 beta Release Notes/Changes in 5.2.6

This page lists fixes/changes in Analytica & ADE beta build 5.2.6 since the previous 5.2.5 beta build.

For what's new since 5.1, see What's new in Analytica 5.2?

Analytica 32-bit

The 32-bit version is currently NOT working. It crashes on startup. Stay tuned.

Graphing

• New graph hover icons for Swap XY, Graph Setup, Uncertainty settings, and unzoom both axes.
• New icon design for the graph axis unzoom hover icon.
• Reduced the delay that determines how long the mouse must be in motion before graph hover icons start to fade in. Was 1 second. Now 100ms (which feels immediate).

• Fixes to these graphing bugs:
  • Undo of swap XY was active but non-functional after closing and re-opening graph window.
  • Crash on undo of graph zoom when graph window is closed before the undo.
  • Undo of graph zoom not working after bringing up and canceling graph setup.
  • Eliminated errors printed to the typescript window when the magic .Probability index for Bands view had been manually scaled.
  • Graph zoom ignores min when include zero is explicit.
  • Graph zoom on Y-axis not working correctly for CDF, PDF plots, or X-axis for Bands, Stats plots (all these axes use special magic indexes).

Clipboard

• Lots of stuff related to pasting between Analytica tables. This area is still in flux for the beta build.

Diagram

• Backed out a change to the visual style of the arrowhead showing external dependencies. We had changed it to a larger gray arrow, but the larger size obscured the arrowheads of actual incoming arrows due to its larger size.

Engine & built-in functions

• Dependency from index to determ table (kids/parent links) got lost after assigning to a DetermTable.
• Subscript does not find image in index.
• Print floating point at full precision, then parse, didn't map to the same value for some numbers. (This was fine in 5.1).
• CanvasDrawEllipse( ) ignored «lineColor» when «lineWidth» was also specified.
• Added a new built-in function: MantissaAndExponent(x), that returns the internal components of a floating point number.
• IRR( ..., guess:-1 ) malfunctioned -- returned NaN. Of course, NPV(rate:-1,...) is always NaN, but IRR needed to look beyond that.

Example Models

• Updated archaic code in the Regression example mode to more modern expression syntax.
• Added a 36x36 example puzzle instance to the Sudoku model. (actually solving it is another thing! Even Gurobi, which solves 5x5 fast, chugs along longer than I was willing to wait).

Tables

• Re-enabled the ability to change cells in an edit table from browse mode when the edit table has an input node. This was inadvertently disabled in the 5.2.5 beta build.
• Odd phantom index slicer appeared in table window after a table index was changed to a zero-length index.
• Column header top border turned white when a row header is clicked.
• Edit table scrambled after adding another index.

User Interface

• When function/object finder opens on Uniform(0,1), is had been opening to the discrete distributions library. Uniform appears in both places -- it can be discrete or continuous depending on the «integer» parameter. Now it opens to the appropriate one.
• The checkboxes in the Uncertainty Setup dialog for 33% and 67% percentiles didn't come up checked when the dialog is opened and 33%,67% are selected.

Optimizer

• Fixed a crash in an «NLP» problem.
