TSP Solver and Generator: TSPSG ChangeLog

TSPSG v0.1.3 beta 1 (build 145)

Solution graph generation.
Support for switching between available Qt styles.
Toolbar customization support (only on desktop platforms).
An option to remember last used directory when saving and opening.
Automatically check for updates at the given interval option (only on Windows platform at this moment).

Improved the solution output generation algorithm. It is now about 1.65 times faster.
Dragging and dropping task file on the main window now opens it.
The deafult output font is now DejaVu LGC Sans Mono and it comes "embedded" in the executable.
The current desktop icon theme in Linux is now used if it follows freedesktop.org icon theme and icon naming spesifications.
Translations are now "embedded" in the executable but may be overrided by placing files with the same names in l10n folder.
Support for Windows 7 Taskbar Extensions (namely, Progress Bars).

About dialog was "tabified". Added GPL License and Credits tabs.
Platform dependent settings (e.g. paths) are saved per-platform.
32x32 icons are used on handheld platforms. This slightly decreases the size of handheld versions. Desktop icons are still 128x128.
Windows binary builds were moved from MSVC to Mingw-w64: no more Visual C++ Runtime dependency.

New TSPSG icon.
Symmetric mode: in this mode the cost of travel from city 1 to city 2 and vice versa is the same.
Printing of solution results (if the platform supports it).
Saving solution to PDF (if the platform supports printing).
An ability to reset all settings to their defaults: hold Shift while clicking Save button in the Settings Dialog.
An ability to generate fractional random numbers.
An ability to set the fractional accuracy (in decimail places).
An ability to select between using native and Qt's file dialogs when opening and saving tasks and solutions.
An ability to disable showing of the solution steps' matrices in solution output.
An ability to enable scroll to the end of the solution output after solving.
An ability ot enable automatic resize of columns and rows to their contents on its change.
Basic support for Symbian.
Check for updates functionality (only in Windows version at this moment).

Improved the solution algorithm.
The maximum number of cities in task was increased to 50.
List of alternate candidates for branching is now displayed.
Warning about possible non-optimal result.
Open a file, passed as command-line argument.
Currently opened file name is displayed in the Main Window title.
"Save Solution" and "Back to Task" buttons in Solution tab for better usability.
The size of the toolbar buttons is now determined based on the device DPI in Windows Mobile and Symbian.
SIP show/hide handling in Windows Mobile.
Toolbar state and position are now saved and restored with the Main Window state and position.
Window translucency support in Windows Vista and Windows 7.

Note:: Showing the solution steps' matrices is disabled by default for tasks with more than 15 cities to considerably speed up the generation of the solution output process.

The resulting path is now sorted, always starts from City 1 and has "City 1 -> City n -> ... -> City 1" format.
Translations were moved from i18n to l10n folder to follow common standards.
Reworked the Settings Dialog layout.
Reworked the About dialog.

A solution couldn't be found for some tasks while the task had at least one solution (mostly, tasks with a lot of restrictions).
An error when loading .zkt file with less than 5 cities.
Generated random numbers were not in the range defined by Minimum and Maximum settings.

This is initial TSPSG release.
