Methods

semantic_eq

static semantic_eq(node1, node2, bit_indices1, bit_indices2)

Check if DAG nodes are considered equivalent, e.g., as a node_match for rustworkx.is_isomorphic_node_match() (opens in a new tab).

Parameters

• node1 (DAGOpNode, DAGInNode, DAGOutNode) – A node to compare.
• node2 (DAGOpNode, DAGInNode, DAGOutNode) – The other node to compare.
• bit_indices1 (dict (opens in a new tab)) – Dictionary mapping Bit instances to their index within the circuit containing node1
• bit_indices2 (dict (opens in a new tab)) – Dictionary mapping Bit instances to their index within the circuit containing node2

Returns

If node1 == node2

Return type

Bool
