Tiles
(x_range, n_tiles, state_components=None)[source]¶ Bases:
object
Class implementing rectangular tiling. For each point in the state space, this class can be used to compute the index of the corresponding tile.

__init__
(x_range, n_tiles, state_components=None)[source]¶ Constructor.
Parameters: - x_range (list) – list of two-elements lists specifying the range of each state variable;
- n_tiles (list) – list of the number of tiles to be used for each dimension.
- state_components (list, None) – list of the dimensions of the input
to be considered by the tiling. The number of elements must
match the number of elements in
x_range
andn_tiles
.

static
generate
(n_tilings, n_tiles, low, high, uniform=False)[source]¶ Factory method to build
n_tilings
tilings ofn_tiles
tiles with a range betweenlow
andhigh
for each dimension.Parameters: - n_tilings (int) – number of tilings;
- n_tiles (list) – number of tiles for each tilings for each dimension;
- low (np.ndarray) – lowest value for each dimension;
- high (np.ndarray) – highest value for each dimension.
- uniform (bool, False) – if True the displacement for each tiling will be w/n_tilings, where w is the tile width. Otherwise, the displacement will be k*w/n_tilings, where k=2i+1, where i is the dimension index.
Returns: The list of the generated tiles.
