Apex Graphs

This module provides functionality related to apex graphs.

pyrigi.graph._other.apex.is_critically_edge_apex(graph)[source]

Return whether the graph is critically edge apex.

Alias for is_critically_k_edge_apex() with k=1.

Return type:

bool

Parameters:

graph (Graph)

Definitions

Critically edge apex graph

pyrigi.graph._other.apex.is_critically_k_edge_apex(graph, k)[source]

Return whether the graph is critically k-edge apex.

Return type:

bool

Parameters:
