Description (last modified by )
Information from Gregg Musiker
I recently realized that if one starts with a digraph D
(with vertices labeled however) and then writes
S = ClusterSeed(D)
, then the code will effectively call
Q = ClusterQuiver(D)
and then assignS = ClusterSeed(Q)
.
In the same spirit as the last ticket, I think it makes sense to add other vertex names to ClusterQuiver
and allow these to be passed on to ClusterSeed
. Since we only changed the behavior of cluster_seed.py
in the last ticket, I believe the behavior of quiver.py
was unaffected.
In particular, if one writes ClusterSeed(D)
or ClusterQuiver(D)
, then I believe Sage should then use the vertices of digraph as labels rather than defaulting to [0,...,n1]
. (Although we will have to think somewhat about backwards compatibility.)
In particular, I'm thinking of two changes.
1) In ClusterQuiver.__init__()
, if a digraph is the input, then the vertices of ClusterQuiver
agree with the labels of the vertices of the input digraph. (Although for internal data, sage would also have a dictionary from {0,..., n1}
to these vertex labels so that it understands the "ijth" entry of the Bmatrix for instance.
2) In ClusterSeed.__init__()
, if a ClusterQuiver
is the input, then it uses those vertices as labels for the cluster variables as if the user had given user_labels
.
The only exception would be if the user puts in such a ClusterQuiver
and also user_labels
as a separate input, then the new user_labels
should override the old ones from the ClusterQuiver
.

Replying to benstrasser:
I changed ClusterQuiver? and ClusterSeed? to maintain lists of mutable and immutable vertices throughout, and ensured that they pass these lists around when necessary. Thus, the user should be able to submit lists of frozen vertices and mutate them freely. Let me know what you think. If these seem like good changes, we can clean up the documentation and finalize.

e9af9bb  allows user to submit a list of frozen vertices, preserves vertex labels when mutated

Hi Ben, These are my suggestions for now:
 In the doc for
ClusterQuiver
taking digraph as input, could you add another linesage: for Q.nlist()
so the user will read thatClusterQuiver
will remember labels from the input digraph.
 The following bug does not exist before this ticket was pulled:
sage: Q=ClusterQuiver(DiGraph([[0,5]])) sage: Q.b_matrix() [ 0 1] [1 0] sage: Q.mutate(0) IndexError: index out of range
 Also, I think we should either explain the following behavior in the doc, or change the code so that the behavior for
mutation
is more consistent. I think either is fine. The following works wellsage: S=ClusterSeed(DiGraph([['a','b']])) sage: S.mutate('a')
but the following throws an error
sage: S=ClusterSeed(DiGraph([[5,'b']])) sage: S.mutate(5) ValueError: The quiver can only be mutated at a vertex or at a sequence of vertices
 If possible, could you get the recent version of Sage (if not 7.3beta 6, then at least 7.2 master branch), and then add your code on top of this recent Sage? Currently your branch is marked as red because it cannot automatically merge.

Some quick comments:
 I believe you want
user_labels
to be a list, so once we switch to Python3, the current code won't work. So I recommend (and is also faster):user_labels = [ZZ(x) if type(x) == int else x for x in user_labels]
 Instead of
elif type(user_labels[i]) in [list,tuple]:
, you should useelif isinstance(user_labels[i], (list, tuple)):
(unless you want to explicitly forbid any subclasses oflist
ortuple
).  Python uses different conventions than, e.g., C++/Java. So variables
isVertices
should beis_vertices
.  You have an erroneous character:

Some comments, most of them are minor:
 There is a
warn
function (see, e.g.,sets/disjoint_union_enumerated_sets.py
). I feel like you should use that instead ofprint
statements, but I'm not 100% sure.  The
copy
is redundant herecopy( list(data._nlist) )
becauselist
already makes a (shallow) copy.  The
keys()
is unnecessary inlabelset = set(user_labels.keys())
.  Do you really only want to test
type(x) == int
in this line:I feel it would be better to douser_labels = [ZZ(x) if type(x) == int else x for x in user_labels]
if x in ZZ
.  If
user_labels
does conflict, are you sure you only want a string printed? This feels like it should be an error.  Change
type(user_labels[key]) in [list,tuple] +isinstance(user_labels[key], (list, tuple))
 You need a blank line here between text and doctests, e.g., here:
There is at least one other place where this is needed.
For a cluster seed from an arbitrarily labelled digraph:: + sage: S = ClusterSeed(DiGraph([['a','b'],['b','c']]),frozen=['b']) sage: S.cluster_class() [[a, c], [a, (b + 1)/c], [(b + 1)/a, c], [(b + 1)/a, (b + 1)/c]]
 From the warning message, I don't understand the added check here:
if frozen is not None and type(frozen) in [int,Integer]: print('The input data is a matrix, therefore the additional parameter frozen is ignored. Frozen vertices read off accordingly if the matrix is not square.')
 Why is this downgraded to only a warning?
+ warning_given = False for edge in dg.edge_iterator():  if edge[0] >= n and edge[1] >= n:  raise ValueError("The input digraph contains edges within the frozen vertices") + if edge[0] >= n and edge[1] >= n and not warning_given: + #raise ValueError("The input digraph contains edges within the frozen vertices") + print('Warning: The input digraph contained edges within the frozen vertices. Use remove_frozen_edges to remove these edges.') + warning_given = True
nlist()
andmlist()
are not very descriptive method names (however, it is fine for the internal attributes). I think it would be better to call themfree_vertices()
andfrozen_vertices()
. Never do
keep_previous_frozen == False
. Simply donot keep_previous_frozen
. Similar forkeep_previous_frozen == True
.  You are breaking PEP8 in a lot of places:
 Arguments should not have spaces around the
=
, e.g.,def foo(x=5)
and notdef foo(x = 5)
.  Same holds true for default arguments to functions.
 Binary operations should have spaces to either side:
strng = strng + "_" + j
. Although IMO you should leave this type aloneuser_labels.keys()[n:n+m]
as the[]
operator takes priority. dict
input as, e.g.,{x: x for x in range(5)}
. Commas will always have spaces after them.
 Arguments should not have spaces around the
 Break long (> 80 characters) docstrings.
 Use
Return
instead ofReturns
in the 1line doc description (at least do not make things worse in your added functions/methods).  There are a number of docstring formatting issues, e.g., you should code format things like
``self``
or variable names.  You have added a lot of unnecessary whitespace to the docstrings. For example:
It is good to be consistent with the rest of Sage (at most 1 line after doctests before the

Thanks for the detailed comments, Travis. I've done my best to address your concerns, although its possible I missed something.
 Some of the 'print('Warning: ... 's which I added were really just clarifying default behavior, so I am not sure they should be warnings. I have removed the `Warning' from this string. I am not sure if this is the correct way to do such a thing in general, but it is at least consistent with the rest of the cluster_algebra_quiver package (see, for example, the messages about ignoring frozen vertices). Perhaps a later ticket should go through and add the
warn
command where appropriate.
 Regarding the warning vs error message for edges between frozen vertices, I had downgraded the error to a warning in order to play nicely with the new
set_frozen
command. I can't remember exactly why Gregg and I decided to add this functionality. Furthermore, this seems to go a bit beyond the stated goals of this ticket. For the moment I've decided to remove theset_frozen
andremove_frozen_edges
methods. I can add these commands (with or without the warning message) with a later ticket if someone wants it.
 I did my best to change 'returns' to 'return' on the docstrings for the methods which we added here. As you point out, this is one of many stylistic inconsistencies throughout the cluster_algebra_quiver package. Perhaps a later ticket could go through and ensure the rest of the package conforms with this. The PEP8 issues are similar  I've done my best to make the new code conform, but there appears to be existing code which doesn't quite follow these standards. If this is a serious issue, someone could try to make the entire package conform with PEP8 at a later date.
Please let me know if I've missed anything of misinterpreted any of your comments!

Replying to benstrasser:

Thanks. I went through and made some additional changes and fixes as well, but there's too much to standardize to do it all on this ticket.

I would say no, but since the rest of the code here does it, it is better to be consistent.

As you point out, this is one of many stylistic inconsistencies throughout the cluster_algebra_quiver package. Perhaps a later ticket could go through and ensure the rest of the package conforms with this. The PEP8 issues are similar  I've done my best to make the new code conform, but there appears to be existing code which doesn't quite follow these standards. If this is a serious issue, someone could try to make the entire package conform with PEP8 at a later date.
Serious, not really. Yet, it makes the code a little more difficult to parse quickly, and it would help give Sage a more polished feel.
If my changes are good, then positive review.

There seems to be a new error found by the patchbot now:
sage t long src/sage/combinat/cluster_algebra_quiver/cluster_seed.py
File "src/sage/combinat/cluster_algebra_quiver/cluster_seed.py", line 2356, in sage.combinat.cluster_algebra_quiver.cluster_seed.ClusterSeed?.mutate Failed example:
S = ClusterSeed?(['A', 4], user_labels=['a', 'b', 'c']);
Expected:
Traceback (most recent call last): ... ValueError?: The number of userdefined labels is not the number of exchangeable and frozen variables.
Got:
<BLANKLINE>
I think once this is fixed, that the code would be ready for a positive review.

Hmm I've run into this kind of issue before... I don't really know how to deal with it since it doesn't seem to occur outside of doctests (i.e. if you manually enter it in terminal). Has anyone seen this before? What tends to cause this?
I'll try to work it out tomorrow.

 Description modified (diff)
It is not a blankline; the patchbot reports an actual error traceback (although the blankline is annoying to have it in the output, it is not something that is actually is checked). It is a simple fix because of changes I made to the error messages to conform to our (and Python's) convention of error messages being lowercase and without periods.
I have also fixed the docbuilding issues reported by the patchbot.

Why use reduce()
here?
is_cluster_vars = reduce(lambda x, y: isinstance(y, str), seqq, 1) and seed._use_fpolys
This code is equivalent to
if len(seqq) == 0 or isinstance(seqq[1], str): is_cluster_vars = seed._use_fpolys else: is_cluster_vars = False
but is that what is intented?
Or did you perhaps mean
is_cluster_vars = all(isinstance(y, str) for y in seqq) and seed._use_fpolys
I ask because we trying to clean this up in #25571.
I am working on a review patch for this ticket. This will include:
1) A small bug fix to address the issue where digraph labels get lost if the ClusterSeed? is mutated:
2) An enhancement allowing users to specify a list of frozen variables.
New commits:
Vertex relabelling based on digraphs
Fix var initialisation
Allow plotting by default as well
