random_reidemeister_move

random_reidemeister_move(k, allow_increase=True, inplace=False)

Performs a random Reidemeister move on a given planar diagram.

Parameters:

• k (PlanarDiagram | OrientedPlanarDiagram) – The planar diagram on which to perform the Reidemeister move.

• allow_increase (str, optional) – Allow to increase the number of crossings. Defaults to True.

• inplace (bool, optional) – Determines whether the move alters the original diagram or creates a new instance. Defaults to False.

Returns:

PlanarDiagram | OrientedPlanarDiagram | None –

The modified planar diagram after

applying the move. Returns None if no applicable move is performed.

Raises:

ValueError – If an unknown move type is encountered.
