edge_differences

Signature/Parameters

def edge_differences(self, G2)

Compare edge sets between two DAGs by edge type.

Parameters:

Name	Type	Description	Default
G2	DAG	Graph to compare with the current instance.	required

Returns:

Type	Description
dict[str, dict[str, list]]	Dictionary with keys 'G1' and 'G2', each mapping to a dictionary keyed by edge type ('directed', 'undirected', 'bidirected') listing edges present in one graph but absent in the other.

Examples:

>>> G1 = DAG(graph="X -> Y")
>>> G2 = DAG(graph="X <- Y")
>>> diff = G1.edge_differences(G2)
>>> diff["G1"]["directed"]
[('X', 'Y')]
