Description
Done here:
- correct method
eulerian_orientation
for graphs without edge (was not using the right set of vertices)- Should we move this method to
orientation.py
?
- Should we move this method to
- some care in
min_spanning_tree
, but we have remaining issues:- algorithm
"Prim_fringe"
compare vertex labels. I addedhash(..)
around, but this is certainly not enough. - the output of min spanning tree methods is sorted. As said in #26547, there is no reason for that.
- algorithm
- avoid a call to .edges in
cycle_basis

Is there a metaticket for files in graphs
? I'm particularly interested in more on generic_graph.py
, especially is_isomorphic
, and also base/sparse_graph.pyx
, especially iterator_edges
. Both of these try to sort vertices, which cause Python 3 doctest failures in homology/simplicial_complexes.py
and homology/examples.py
.

Let us use #26640 as meta ticket. Should have been opened earlier. Feel free to modify it as I don't know how to organize it.
