auto
(nodes: Iterable[tensornetwork.network_components.AbstractNode], output_edge_order: Optional[Sequence[tensornetwork.network_components.Edge]] = None, memory_limit: Optional[int] = None, ignore_edge_order: bool = False) → tensornetwork.network_components.AbstractNode¶ Chooses one of the above algorithms according to network size.
Default behavior is based on
opt_einsum
’sauto
contractor.Parameters: - nodes – A collection of connected nodes.
- output_edge_order – An optional list of edges.
Edges of the final node in
nodes_set
are reordered intooutput_edge_order
; if final node has more than one edge,output_edge_order
must be provided. - memory_limit – Maximum number of elements in an array during contractions.
- ignore_edge_order – An option to ignore the output edge order.
Returns: Final node after full contraction.
