No idea why anyone would want that, but there you have it.\n\n\nCredits\n-------\n\nSee TSPLIB_ for original details, including file format specification, C++ code, and sample problems.\n\nThis package was created with Cookiecutter_ and the `audreyr/cookiecutter-pypackage`_ project template.\n\n.. _Cookiecutter: https://github.com/audreyr/cookiecutter\n.. _`audreyr/cookiecutter-pypackage`: https://github.com/audreyr/cookiecutter-pypackage\n\n.. _TSPLIB: https://www.iwr.uni-heidelberg.de/groups/comopt/software/TSPLIB95/index.html\n\n\n=======\nHistory\n=======\n\n0.6.0 (2019-10-19)\n------------------\n\n* Changes to the conversion into a ``networkx.Graph``:\n\n    * Depot, demand, and fixed edge data have been removed from graph metadata.\n      Depot and demand data is now associated with individual nodes like fixed edge\n      data was (and still is).\n    * Add a ``normalized`` parameter to allow nodes to be renamed as zero-index\n      integers when obtaining a ``networkx.Graph``.\n\n* Depots, demands, node coordinates, and display data fields now default to\n  empty containers rather than ``None``.\n* Fixed twine/PyPI warning about long description mime type\n\n\n0.5.0 (2019-10-02)\n------------------\n\n* New loaders that take just the text - no file necessary!\n* Invalid keywords now result in a ``ParsingError``\n* Update the CLI to catch and gracefully handle ``ParsingError``\n* Fixed a bug when trying to amend an exception with line information\n\n\n0.4.0 (2019-09-21)\n------------------\n\n* All expected parsing errors are now raised as ``ParsingError`` rather than the base ``Exception`` type.\n* Fix name of distance paramter to distances.geographical. Previously it was \"diameter\" but was used as a radius. It is now \"radius\".\n* Relax restriction on networkx version (now ``~=2.1``)\n* Add documentation for each problem field\n* Other minor documentation changes\n* Add offical 3.7 support\n* Add missing history entry for v0.3.3\n* Remove some dead code\n\n0.3.3 (2019-03-24)\n------------------\n\n* Fix parsing bug for key-value lines whose value itself contains colons\n\n0.3.2 (2018-10-07)\n------------------\n\n* Fix bug in ``Problem.is_complete`` that produced a ``TypeError`` when run\n* Fix bug in ``Problem.is_depictable`` that produced a ``TypeError`` when run\n* Fix bug in ``Problem.get_display`` that produced an ``AttributeError`` when run\n* Added some unit tests for the ``Problem`` class\n* Added some unit tests for the ``parser`` module\n\n0.3.1 (2018-10-03)\n------------------\n\n* Fix bug in ``Problem.is_weighted`` that caused problems with defined nodes\n  coords to use the unit distance function\n\n0.3.0 (2018-08-12)\n------------------\n\n* Added XRAY1 and XRAY2 implementations\n* Simplified some of the matrix code\n\n0.2.0 (2018-08-12)\n------------------\n\n* Implement column-wise matrices\n* Add a utiltiy for loading an unknown file\n* Fix bug in the ATT distance function\n* Update the CLI to use the models\n* Document a bunch-o-stuff\n* Switch to RTD sphinx theme\n* Move most utilties into utils\n\n0.1.0 (2018-08-12)\n------------------\n\n* First release on PyPI.\n\n\n",
