compute_S_hat0¶

safemdp.compute_S_hat0(s, world_shape, n_actions, altitudes, step_size, h)¶

Compute a valid initial safe seed.

s: int or nan: Vector index of the state where we start computing the safe seed from. If it is equal to nan, a state is chosen at random
world_shape: tuple: Size of the grid world (rows, columns)
n_actions: int: Number of actions available to the agent
altitudes: np.array: It contains the flattened n x m matrix where the altitudes of all the points in the map are stored
step_size: tuple: step sizes along each direction to create a linearly spaced grid
h: float: Safety threshold
