PT connection syntax
====================

Starting from v0.4.0, SoyutNet supports a simpler syntax for connecting
places and transitions by overloading operators ``>>, <<, >, <``.

* :py:meth:`soyutnet.pt_common.PTCommon.__rshift__`
* :py:meth:`soyutnet.pt_common.PTCommon.__lshift__`
* :py:meth:`soyutnet.pt_common.PTCommon.__gt__`
* :py:meth:`soyutnet.pt_common.PTCommon.__lt__`

Graph format
------------

* Places are represented by circles with labels :math:`p_i`.
* Transitions are represented by boxes with labels :math:`t_i`.
* Arcs are arrows with labels in the form of ':math:`w ~ \{l_1, l_2, \dots \}`'.
    * :math:`w` is the weight of arc.
    * :math:`\{l_i\}` is the arc labels meaning that a particular arc
      accepts :ref:`tokens <token-def>` with a label in the set :math:`\{l_i\}`.
    * If arc has no label, then it has the default label ':math:`1 \{0\}`'.
