egttools.plotting.helpers.perturb_state_discrete

perturb_state_discrete(state, size, perturbation=1)

Produces a number of points in the simplex close to the state.

If the sate is a vertex or in an edge, the perturbation is only made across the edges (we don’t look for points in the interior of the simplex).

Parameters

• state (Union[Tuple[float, float, float], numpy.ndarray]) – The barycentric coordinates of a point inside the simplex.

• size (int) – The size of the edges of the simplex. This should coincide with the size of the finite population in Moran dynamics.

• perturbation (int) – The amount of perturbation to apply to the point.

Returns

A list of points (in barycentric coordinates) which are close to the state in the simplex.

Return type

List[numpy.ndarray]
