This is probably a very silly question. How does one get the edge isoperimetric number of a graph?
As seen under this link [which I cannot put correctly due to low karma] trac.sagemath.org/ticket/21942 there should be an algorithm for it, but when I define a graph (say H), then
edge_isoperimetric_number(H)
returns "name 'edge_isoperimetric_number' is not defined"
and
H.edge_isoperimetric_number()
returns "'Graph' object has no attribute 'edge_isoperimetric_number'"
(while
edge_isoperimetric_number?
returns "Object edge_isoperimetric_number not found."
So how do I load said algorithm for use?
