Method add_edge

pyvrp/Model.py:314–346

Adds an edge :math:`(i, j)` between ``frm`` (:math:`i`) and ``to`` (:math:`j`). The edge can be given distance and duration attributes. Distance is required, but the default duration is zero. Returns the created edge. .. note:: If ``profile`` is

           If ``profile`` is not provided, the edge is a base edge that will be

           locations.

           If called repeatedly with the same ``frm``, ``to``, and ``profile``
           arguments, only the edge constructed last is used. PyVRP does not
           support multigraphs.
