Hello all igraphers!
I am using an old version of the library on an old Fedora machine.
When I build a tree, using:
g=igraph.Graph.Tree(100,3)
and then write the graph to a file (GML format) the result is a
directed graph: the GML file reads:
Creator "igraph version 0.5 Fri Jun 26 12:31:25 2009"
Version 1
graph
[
directed 1
....
Which is not obvious, since the Tree() should default to
"type=TREE_UNDIRECTED".
Is that a glitch in the old version I am using, or it's a bug?
And if it is the latter, has it been fixed in more recent versions?
Is there a fix without updating?
I guess I should update, but I don't know if the admin will let me :)
Thanks,
marco
