================== TSPSG v0.1 beta 1 Release README ==================

Release Notes


TSPSG was built under Kubuntu Linux 10.10 using Qt 4.7.0. It depends on the following packages: libqt4-core, libqt4-gui, libqt4-svg and all required dependencies. In some distributions Qt imageformats plugins may come as a separate package, so to get support of additional image formats for solution graph export you may also need to install this package.

NOTE: Please, note that package names may differ in your distribution. For example, libqt4-core may be named as qt-core. Just be sure that you install Qt 4.7.0 or later.


TSPSG supports Windows XP and higher, 32-bit and 64-bit versions.

The Installer contains both 32-bit and 64-bit builds and installs the one according to your system.

Windows Mobile

TSPSG supports Windows Mobile 5.0 Pocket PC edition and higher. Minimal recommended resolution is QVGA (240x320).

  1. TSPSG-v0.1-alpha2-shared.cab
    This build of TSPSG uses shared Qt libraries. The free storage space requirements are high (~11 MB) but it uses less RAM (~3.5 MB for a 5-city task).

  2. TSPSG-v0.1-alpha2-static.cab
    Static build of TSPSG compressed with UPX. It has a smaller free space requirements (~2.6 MB) but uses much more RAM (~10 MB for 5-city task).


TSPSG was built under FreeBSD 6.3 using Qt 4.6.3. The following packages/ports are required to be able to run it: devel/qt4-corelib, x11-toolkits/qt4-gui, graphics/qt4-svg and all required dependencies. To get support of additional image formats for solution graph export you may also install graphics/qt4-imageformats package/port.

NOTE: Please, note, that FreeBSD build is highly experimental as it has not been tested.


TSPSG v0.1 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.


  • Solution related actions not disabled when solution is canceled.
  • "Autosize" setting was never saved and was always on.

TSPSG v0.1 alpha 2 (build 100)


  • 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. 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.
  • 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.


  • 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.

TSPSG v0.1 alpha 1 (build 42)

This is initial TSPSG release.


  • Solving taks with up to 5 cities.
  • Generating tasks.
  • Saving solution results to HTML and ODF.
  • Importing tasks from ZKomModRd.
  • Multilinguality: English, Russian and Ukrainian languages.
  • Linux/UNIX, Windows and Windows Mobile support.
