Use this if you are using igraph from R
Two graphs are considered identical by this function if and only if they are represented in exactly the same way in the internal R representation. This means that the two graphs must have the same list of vertices and edges, in exactly the same order, with same directedness, and the two graphs must also have identical graph, vertex and edge attributes.
identical_graphs(g1, g2, attrs = TRUE)
The two graphs
Whether to compare the attributes of the graphs
This is similar to
identical in the
but it ignores the mutable piece of igraph objects; those might be
different even if the two graphs are identical.
Attribute comparison can be turned off with the
attrs parameter if
the attributes of the two graphs are allowed to be different.
