Ticket #26640 – Description
v62 v63 6 6  direct comparison of vertex labels (e.g., in method `iterator_edges` of `base/sparse_graph.pyx`) 7 7  methods using matrices: `adjacency_matrix`, `distance_matrix`, etc. For all these methods, we can now give as input an ordering of the vertices that will be used to order rows and columns. Currently, we use `.vertices()` by default. If we switch to `list(G)` by default, we have to check that it's not breaking algorithms using these matrices. 8  sort used in methods for checking isomorphisms w/wo edge labels 8  sort used in methods for checking isomorphisms w/wo edge labels (see also #27232 and #26800). Sorting of lists of possibly unhashable objects is needed here, or may be a method for checking that there is a permutation from one list to the other could be enough ? 9 9 10 10 … … 13 13  #26800 py3: bug with `canonical_label` 14 14  #27232 `is_permutation_of` broken for matrices over cyclotomic fields  this is due to `is_isomorphic` in graphs. 15  `sage.graphs.graph_database`: there is a failing doctest in py3 with `interactive_query`... 16 15  #27435 py3: failing doctest in `graph_database.py` with `interactive_query` 17 16 18 17 '''Needs review''': … … 20 19  #27137 pep8 in `digraph_generators.py` (part 4) 21 20  #27138 pep8 in `digraph_generators.py` (part 5) 22  #27408 Edge view for graphs 21  #27408 Edge view for graphs  introduce deprecation warning for `sort=None` as the plan is to set `sort=False` by default. 23 22 24 23
