gate_lr_old.gate_string_reduce_split_(TG, where, string, original_ts, bonds_along, reindex_map, site_ix, info, **compress_opts)¶

gate_lr_old.gate_2d_long_range(self, G, where, contract=False, tags=None, inplace=False, info=None, long_range_use_swaps=False, long_range_path_sequence=None, **compress_opts)¶

gate_lr_old.gen_long_range_path(ij_a, ij_b, sequence=None)¶

Generate a string of coordinates, in order, from ij_a to ij_b.

Parameters:

ij_a ((int, int)) – Coordinate of site ‘a’.
ij_b ((int, int)) – Coordinate of site ‘b’.
sequence (None, iterable of {'v', 'h'}, or 'random', optional) – What order to cycle through and try and perform moves in, ‘v’, ‘h’ standing for move vertically and horizontally respectively. The default is ('v', 'h').

Returns:

The path, each element is a single coordinate.

Return type:

generator[tuple[int]]

gate_lr_old.gen_long_range_swap_path(ij_a, ij_b, sequence=None)¶

Generate the coordinates or a series of swaps that would bring ij_a and ij_b together.

Parameters:

ij_a ((int, int)) – Coordinate of site ‘a’.
ij_b ((int, int)) – Coordinate of site ‘b’.
sequence (None, it of {'av', 'bv', 'ah', 'bh'}, or 'random', optional) – What order to cycle through and try and perform moves in, ‘av’, ‘bv’, ‘ah’, ‘bh’ standing for move ‘a’ vertically, ‘b’ vertically, ‘a’ horizontally’, and ‘b’ horizontally respectively. The default is ('av', 'bv', 'ah', 'bh').

Returns:

The path, each element is two coordinates to swap.

Return type:

generator[tuple[tuple[int]]]

gate_lr_old.swap_path_to_long_range_path(swap_path, ij_a)¶: Generates the ordered long-range path - a sequence of coordinates - from a (long-range) swap path - a sequence of coordinate pairs.
