is_factor_critical property has mistake in docstring #616

Closed math1um closed 3 years ago

math1um commented 3 years ago

SHOULD BE:

sage: is_factor_critical(graphs.PathGraph(3)) True

OLD:

def is_factor_critical(g): """ Return whether or not a graph "g" is factor-critical.

A graph is factor-critical if order is odd and removal of any vertex gives graph with perfect matching

INPUT:

-``g``-- Sage graph

OUTPUT:

-Boolean value

EXAMPLES:

    sage: is_factor_critical(graphs.PathGraph(3))
    False

    sage: is_factor_critical(graphs.CycleGraph(5))
    True
