Normaliz can compute Hilbert series of the integral closures of monomial ideals, not of arbitrary monomial ideals. If one wants to apply it: input the monomials as vertices, the polynomial ring as cone (= unit matrix), and put the weights of the indeterminates into the grading.
Example for Normaliz input (integral closure of (x^{2, y}2, deg x = 2, deg y =1)
amb_space 2 vertices 2 2 0 1 0 2 1 cone 2 1 0 0 1 grading 2 1 HilbertSeries

Thank you. But my question was really: Given a monomial ideal in Sage, how to compute the Hilbert series of it (or maybe of its integral closure) using normaliz as a backend (not: in normaliz).
I.e.:
sage: n=4;m=11;P = PolynomialRing(QQ,n*m,"x"); x = P.gens(); M = Matrix(n,x) sage: I = P.ideal(M.minors(2)) sage: J = P*[m.lm() for m in I.groebner_basis()]
and what now? How to use the new interface to normaliz to compute the Hilbert series of (the integral closure of) J
?
Since I never worked with the integral closure of a monomial ideal: How are the Hilbert series of the ideal and its integral closure related?
comment:33 Changed 4 years ago by
"What now?" is a question that JeanPhilippe should answer. I have no overview which of the Normaliz computation goals can be reached from Sage. However, all of them can be reached via PyNormaliz?. For example, Normaliz can take a binomial ideal (suitably encoded) as input. It finds the affine monoid A defined by the binomial ideal, and then computes invariants of the normalization of A.
I think there is no way to relate the Hilbert series of an ideal I and the Hilbert series of its integral closure in a useful way.

My knowledge of the theory lacks in order to give you a satisfactory answer to your questions.
The present ticket allows you to get the Hilbert series of a rational polyhedron. Whether this Hilbert series is or corresponds to the Hilbert series of a monomial ideal should be clarified. In case they match, then, what I would do in Sage is
1) a function that transfers the data of the monomial ideal to a polyhedron that uses the backend normaliz and compute its hilbert series (a function implemented in this ticket).
2) use PyNormaliz? package directly as the normaliz backend of polyhedron is currently doing. This is not really well documented as its usage is currently only in the backend for polyhedron.
For this, the present ticket provides some useful functions to deal with PyNormaliz? that builds on #25090.
comment:35 Changed 4 years ago by
Would this compute what you want? I did this with the current ticket and merge with the latest sage.
sage: n=4;m=11;P = PolynomialRing(QQ,n*m,"x"); x = P.gens(); M = Matrix(n,x) sage: I = P.ideal(M.minors(2)) sage: J = P*[m.lm() for m in I.groebner_basis()] sage: P = Polyhedron(rays=[m.degrees() for m in J.gens()],backend='normaliz') sage: P A 42dimensional polyhedron in ZZ^44 defined as the convex hull of 1 vertex and 330 rays sage: P.hilbert_series()
Well, I'd say this is a quite large computation involving triangulating a 42 dimensional polyhedron with 330 vertices...
comment:36 Changed 4 years ago by
What one really wants is not the Hilbert series of the ideal. The goal is the Hilbert series of the residue class ring defined by the ideal. The residue class ring can be identified with a monomial algebra of Krull dimension 14. The Hilbert series is easily calculated. If one wants to use Normaliz for it, then the best approach is to input the binomial ideal to Normaliz.
You make a matrix of integer vectors whose rows represent the binomials in the form vw, corresponding to x^{v  x}w. The input type is "lattice_ideal". You must also define a grading. Simply say "total_degree". In this case it represents a vector with 44 entries 1.
That one can go this way is due to the fact that the residue class ring is a normal monoid algebra. In general this is not the case.

Yes, it doesn't. But I guess that's because the author of that ticket thought that the solution is relatively straight forward: When you code in Python, how do you use a package? You do so by importing stuff. Hence, you should test whether the package is available by trying to import something from that package (sooner or later, you will do anyway!), surrounded with a try: ... except ImportError: ...
clause.
Indeed, in your code, you do import PyNormaliz
. So, this could be
try: import PyNormaliz except ImportError: raise ImportError("some meaningful error message, telling the user at least one way to install PyNormaliz")
For latte_int, I am not so sure what you do, because I don't see a related import statement in your code. However, in some place of your code, you do use it; you should try and see what happens if latte_int is not available: Will there be an ImportError, or a TypeError, or a ValueError, etc.? Then, instead of is_package_available
, you could try to use latte_int in a dry run, and if an error occurs, you take it as an answer (namely the answer that latte_int is not available).

I looked back at this now, and I'm getting a weird result from an example in Normaliz' manual:
sage: P = Polyhedron(vertices=[(1/2,1/2),(1/3,1/3),(1/4,1/2)],backend='normaliz') sage: P A 2dimensional polyhedron in QQ^2 defined as the convex hull of 3 vertices sage: P.hilbert_series() 0
From calling PyNormaliz?, I get:
sage: h = PyNormaliz.NmzResult(new_cone, "HilbertSeries") sage: h [[], [], 1L]
So it's not the parsing from PyNormaliz? to sage, but rather something weird is happening here. It has been a while since I wrote the code so I am a bit lost in trying to figure out what is going on...
I'll try to do some more searching...
comment:47 followup: ↓ 48 Changed 4 years ago by
I guess you want the Ehrhart series. The Normaliz computation goal HilbertSeries? requires the existence of a grading which is not defined with this input.
This is an intricate point, but it is inevitable: the grading is defined on the space in which the polyhedron lives, not on the cone over it.

Yes, in the end I want the Ehrhart series, but I was doing both computations to understand their difference again...
This is an intricate point, but it is inevitable: the grading is defined on the space in which the polyhedron lives, not on the cone over it.
Yes, agreed. I take this example from p.23 of the Normaliz manual. I thought that HilbertSeries? would work out of the box like in the example. That's why I am asking myself what I did wrong.
In the code for hilbert_series, if no grading is given, we canonically give the all 1's grading on the ambient space, and then ask for the HilbertSeries?, in which case we get the empty result(!?). (Is that a good choice of canonical grading?)
So, my question would be, how do I get the result from the Normaliz manual?
This issue makes me wonder also if the results in the current examples are actually true (because maybe I am doing something wrong). For example, what would be the expected outputs of for the 3dimensional 01 cube?
Currently it gives me:
sage: C = Polyhedron(vertices = [[0,0,0],[0,0,1],[0,1,0],[0,1,1],[1,0,0],[1,0,1] ....: ,[1,1,0],[1,1,1]],backend='normaliz') sage: C.hilbert_series() t^3 + 3*t^2 + 3*t + 1 sage: C.ehrhart_series() (t^2 + 4*t + 1)/(t^10  t^9  t^8 + 2*t^5  t^2  t + 1) sage: C.ehrhart_series().denominator().factor() (t + 1)^2 * (t  1)^4 * (t^2 + 1) * (t^2 + t + 1) sage: C.ehrhart_quasipolynomial() t^3 + 3*t^2 + 3*t + 1
Hilbert series and ehrhart polynomials look fine, but the denominator of the Ehrhart series is not what I would expect. Is that related to the discussion on p.24 of Normaliz' manual?
I would have expected (1t)^{4, so that the degree would be 2 so that when we dilate by a factor two, we see the first interior integer point. Right? }
comment:49 Changed 4 years ago by
HilbertSeries? works out of the box, provided you use the right input type:
polytope defines a cone and a grading, and the Hilbert series of the cone under this grading is the Ehrhart series of the polytope that arises as the intersection of the cone and the hyperplane of degree 1 elements. polytope is a homogeneous input type.
The inhomogeneous type vertices only defines a polytope P, or in connection with cone a potentially umbounded polyhedron. We can have an grding on the space in which the polytope lives, and then HilbertSeries? makes sense. This Hilbert series is the generating function of the lattice point enumerator of the points in P. You can ask Normaliz to compute the Ehrhart series of P if P is bounded. It constructs a cone with a grading behind the scenes and computes the Hilbert series of that cone.
So far, so good.
In your cube example: the vertices are in principle rational vectors. What are your denominators? Does Sage choose them automatically? If so what are they?
Moreover, it seems to me tat Sage implicitly defines a grading on the space of the polytpe, taking the sum of the coordinates. This explains why you get a Hilbert series and that it is exactly the result shown: 1 point of degree 0, 3 points of degree 1, 3 of degree 2 and 1 of degree 3.
The denominator of the Ehrhart series is for a 3dimensional polytope that has vertices of degree 4,3,2 qnd 1.
Before I can say more, I must know what happens on the way from Sage input to Normaliz input.
comment:50 Changed 4 years ago by
PS. My question for the denominators must be understood form the viewpoint of Normaliz input. For the 3cube we need vertices with four coordinates in Normaliz where the last coordinate represents a denominator for the first three. (This was introduced before Normaliz allowed fractions in input; it would be superfluous now.)
If you send the matrix with the 8 vertices as it is to Normaliz as input type vertices, then the result will be a BadInputexception?, because we have the denominator 0 for some vertices. In other words: Something must have happened from the Sage vertices before they go into Normaliz.
I think you want the denominator 1 attached to each vertex. If we do that, the Normaliz input becomes
amb_space auto vertices [[0,0,0,1],[0,0,1,1],[0,1,0,1],[0,1,1,1],[1,0,0,1],[1,0,1,1],[1,1,0,1],[1,1,1,1]] EhrhartSeries
and the output contains
Ehrhart series: 1 4 1 denominator with 4 factors: 1: 4
as one expects.
Again my question: what happens on the way from Sage input to Normaliz input?
comment:51 Changed 4 years ago by
Dear Winfried,
Thanks for your quick reply. This explanation is really good, and probably I should add it to the top to shortly describe how the translation from sage to normaliz is done.
Here is the verbose of the example for the cube, we can see the input given by sage to normaliz. The current way is to always use inhomogeneous (vertices, cones, and subspaces). Eventually, inhom. equations and inequalities are added.
sage: C = Polyhedron(vertices = [[0,0,0],[0,0,1],[0,1,0],[0,1,1],[1,0,0],[1,0,1],[1,1,0],[1,1,1]],backend='normaliz', ....: verbose=True) # Calling PyNormaliz.NmzCone(**{'subspace': [], 'vertices': [[0, 0, 0, 1], [0, 0, 1, 1], [0, 1, 0, 1], [0, 1, 1, 1], [1, 0, 0, 1], [1, 0, 1, 1], [1, 1, 0, 1], [1, 1, 1, 1]], 'cone': []}) # 8< Equivalent Normaliz input file 8< amb_space 3 subspace 0 vertices 8 0 0 0 1 0 0 1 1 0 1 0 1 0 1 1 1 1 0 0 1 1 0 1 1 1 1 0 1 1 1 1 1 cone 0 # 8<8<8<
Once I have this, I compute the hilbert series, without giving any grading. In this case, Sage assign the grading [1,...,1] and passes it to normaliz (as you observed) and get:
sage: C.hilbert_series() t^3 + 3*t^2 + 3*t + 1
Now, for the Ehrhart series, I get:
sage: C.ehrhart_series() (t^2 + 4*t + 1)/(t^10  t^9  t^8 + 2*t^5  t^2  t + 1)
As you said:
It constructs a cone with a grading behind the scenes and computes the Hilbert series of that cone.
What is the grading in this case?
So there seems to be a difference between the above input and the one you mentioned:
amb_space auto vertices [[0,0,0,1],[0,0,1,1],[0,1,0,1],[0,1,1,1],[1,0,0,1],[1,0,1,1],[1,1,0,1],[1,1,1,1]] EhrhartSeries
because they give different output for the Ehrhart series?

The Normaliz input is the desired one. If I run it with the computation goal EhhhartSeries? I get the right answer, and if I run it with the computation goal HilbertSeries?, then the answer is that it cannot be computed. Everything o.k.
But it is also clear that this workflow is not exactly that of Sage/PyNormaliz?: the latter constructs a cone and then calls functions that trigger computations and return results. For a better analysis the next step is to put the same data into PyNormaliz? and to see what happens.

Ok, I will look into that.

Ok, I think that I have figured out something, that I did not expect.
sage: C = Polyhedron(vertices = [[0,0,0],[0,0,1],[0,1,0],[0,1,1],[1,0,0],[1,0,1],[1,1,0],[1,1,1] ....: ],backend='normaliz',verbose=True) # Calling PyNormaliz.NmzCone(**{'subspace': [], 'vertices': [[0, 0, 0, 1], [0, 0, 1, 1], [0, 1, 0, 1], [0, 1, 1, 1], [1, 0, 0, 1], [1, 0, 1, 1], [1, 1, 0, 1], [1, 1, 1, 1]], 'cone': []}) # 8< Equivalent Normaliz input file 8< amb_space 3 subspace 0 vertices 8 0 0 0 1 0 0 1 1 0 1 0 1 0 1 1 1 1 0 0 1 1 0 1 1 1 1 0 1 1 1 1 1 cone 0 # 8<8<8<
So far I simply created the 01cube using normaliz. Then, I get the normaliz cone and the enclosed data:
sage: cone = C._normaliz_cone;cone <capsule object "Cone" at 0x7fcc880cf210> sage: data = C._get_nmzcone_data()
From there, if I compute the Hilbert Series directly, it will complain, because it does not have a grading:
sage: PyNormaliz.NmzResult(cone,"HilbertSeries")  error Traceback (most recent call last) <ipythoninput2693c9989a5377> in <module>() > 1 PyNormaliz.NmzResult(cone,"HilbertSeries") error: Could not compute: No grading specified and cannot find one. Cannot compute some requested properties!
So far so good. Then, I ask for the Ehrhart series and then, it unlocks the Hilbert series:
sage: PyNormaliz.NmzResult(cone,"EhrhartSeries") [[1L, 4L, 1L], [1L, 1L, 1L, 1L], 0L] sage: PyNormaliz.NmzResult(cone,"HilbertSeries") [[1L, 4L, 1L], [1L, 1L, 1L, 1L], 0L]
For now, there is no way to access the difference in the normaliz cone. It is now equipped with a grading in the background, but it seems that we can not extract it:
sage: new_C = C.parent().element_class._from_normaliz_cone(parent=C.parent(),normaliz_cone=cone) sage: PyNormaliz.NmzResult(new_C._normaliz_cone,"HilbertSeries") [[1L, 4L, 1L], [1L, 1L, 1L, 1L], 0L] sage: PyNormaliz.NmzResult(new_C._normaliz_cone,"Grading")  error Traceback (most recent call last) <ipythoninput43809cb91899e5> in <module>() > 1 PyNormaliz.NmzResult(new_C._normaliz_cone,"Grading") error: Could not compute: Grading !
But, when creating a whole new cone from the data and adding by hand the grading (which is what is done in hilbert_series
in sage, we get the enumeration of the lattice points with respect to this grading:
sage: C.hilbert_series() t^3 + 3*t^2 + 3*t + 1
This can be reproduced manually as:
sage: data['grading'] = [1] * C.ambient_dim() sage: new_cone = C._make_normaliz_cone(data) sage: h = PyNormaliz.NmzResult(new_cone, "HilbertSeries");h [[1L, 3L, 3L, 1L], [], 0L]
So, right now, we get two potential output for Hilbert series.
Further, if we actually change the normaliz cone while doing the computation of the Hilbert series (instead of doing it on a distinct cone created on the side), it then breaks the ehrhart series:
sage: C._normaliz_cone = new_cone sage: C.ehrhart_series()  error Traceback (most recent call last) <ipythoninput850117d93a819f> in <module>() > 1 C.ehrhart_series() /home/jplabbe/sage/local/lib/python2.7/sitepackages/sage/geometry/polyhedron/backend_normaliz.pyc in ehrhart_series(self, variable) 636 637 cone = self._normaliz_cone > 638 e = PyNormaliz.NmzResult(cone, "EhrhartSeries") 639 640 from sage.rings.polynomial.polynomial_ring_constructor import PolynomialRing error: Some error in the normaliz input data detected: Grading not allowed with Ehrhart series in the inhomogeneous case
Oi Oi Oi...
comment:55 Changed 4 years ago by
Everything above is as it should be, with 2 exceptions:
1) The computation of the Ehrhart series should not make the Hilbert series computed. This requires a correction in libnormaliz.
There is no grading in the background. The Ehrhart series was computed on an auxiliary cone.
2) Sage should not add a default grading if one asks for the Hilbert series. This is not in my hands.
Further remark: if one changes the grading later on (or defines one), all grading dependent results are erased.
comment:56 Changed 4 years ago by
PS. The last observation is the intended behavior of Normaliz: HilbertSeries? and EhrhartSeries? are not allowed on the same input. One intended obstruction to this is that we do not even allow a grading if EhrhartSeries? is to be computed.
comment:57 Changed 4 years ago by
The next Normaliz release will store the Hilbert series and the Ehrhart series separately and provide a specific access function for the Ehrhart series. Then the confusion that we see in the preceding remarks will not arise anymore.
comment:58 Changed 4 years ago by
Ok!!
So I went back to PyNormaliz? and had a look at the tutorial mentioned in Appendix E of the normaliz manual:
https://mybinder.org/v2/gh/Normaliz/NormalizJupyter/master
In there, the PyNormaliz? output of .hilbert_series is explained. Importantly, it seems that the output is different than the one of normaliz(!). This was the source of one of the above problems.
[[1L, 4L, 1L], [1L, 1L, 1L, 1L], 0L]
As to be interpreted as t^2+4t+1
divided by (1t)(1t)(1t)(1t)
and a 0
shift.
So, it's all good. But it indicates that the code should be more explicit on those output formats... I'll put this on my list of TODO to add on some comments on the pynormaliz side...
comment:59 followup: ↓ 61 Changed 4 years ago by
In the Normaliz pitput file we use a multiset notation. i think this is difficult to represent in Python. Therefore it is translated into a vector format where each element of the multiset is repeated as often as it occurs in the multiset.

Yes, makes sense now. Somehow got it wrong from the beginning. I just commited an update that should cover the mistake. I added several examples coming from normaliz manual to be able to compare.
I still have to smoothen the usage for the user. But now, at least things look like they work and make sense...

Here is a bug, which I think is coming from the PyNormaliz? side of things:
sage: v = [[0,0,0],[0,0,1],[0,1,0],[0,1,1],[1,0,0],[1,0,1],[1,1,0],[1,1,1]] sage: cube = Polyhedron(vertices=v,backend='normaliz') sage: cube._volume_normaliz() sage: cube._volume_normaliz('induced_lattice') 6 sage: cube._volume_normaliz() 1.0
Equivalently:
sage: v = [[0,0,0],[0,0,1],[0,1,0],[0,1,1],[1,0,0],[1,0,1],[1,1,0],[1,1,1]] sage: cube = Polyhedron(vertices=v,backend='normaliz',verbose=True) # Calling PyNormaliz.NmzCone(**{'subspace': [], 'vertices': [[0, 0, 0, 1], [0, 0, 1, 1], [0, 1, 0, 1], [0, 1, 1, 1], [1, 0, 0, 1], [1, 0, 1, 1], [1, 1, 0, 1], [1, 1, 1, 1]], 'cone': []}) # 8< Equivalent Normaliz input file 8< amb_space 3 subspace 0 vertices 8 0 0 0 1 0 0 1 1 0 1 0 1 0 1 1 1 1 0 0 1 1 0 1 1 1 1 0 1 1 1 1 1 cone 0 # 8<8<8< sage: cone = cube._normaliz_cone sage: import PyNormaliz sage: PyNormaliz.NmzResult(cone,'EuclideanVolume') sage: PyNormaliz.NmzResult(cone,'EuclideanVolume') 1.0
This is weird. The volume somehow seems to get lost on the way. When one asks again, the output appears.

I have some comments:
This is a general Python convention we try to follow with the messages, moreover, the error is because the class has the wrong type (you are not expecting it to be implemented at some point, right?):
raise NotImplementedError("The backend should be normaliz.") +raise TypeError("the backend should be normaliz")
A similar comment applies elsewhere too. However, the ImportError
can be the exception to this guide as it is "long".
The INPUT:
bullet points are not considered to be complete sentences, so they should not end in a period/fullstop.
PEP8:
sage: S = Polyhedron(vertices = [[0,1],[1,0]],backend='normaliz') # optional  pynormaliz +sage: S = Polyhedron(vertices=[[0,1],[1,0]], backend='normaliz') # optional  pynormaliz
and similar such things.
In ehrhart_series()
, i think this will look better in latex formatting:
``t^k`` is number of integer lattice points inside the ``k``th dilation of +`t^k` is number of integer lattice points inside the `k`th dilation of
Note that k
and t
are not input variable names.

I think I ended up being a little vague about the error messages. In Python, error messages start with a lowercase letter and do not end with a period/fullstop. While I do not expect you to change them all, I think it is good not to make it further from the general convention. I know this is not documented, but is sort of an agreement. So if you want to keep things the way they are, then you can go ahead and set a positive review. Although I would appreciate you changing them (or at least making a uniform convention for all of your added error messages).

In def _cone_generators(pynormaliz_cone):

/home/uqtscrim/sagebuild/local/lib/python2.7/sitepackages/sage/geometry/polyhedron/backend_normaliz.pyc in _nmz_result(self, normaliz_cone, property) 193 PythonModule("PyNormaliz", spkg="pynormaliz").require() 194 import PyNormaliz > 195 return self._nmz_result(normaliz_cone, property) 196 197 def _init_from_normaliz_cone(self, normaliz_cone): ... last 1 frames repeated, from the frame below ... /home/uqtscrim/sagebuild/local/lib/python2.7/sitepackages/sage/geometry/polyhedron/backend_normaliz.pyc in _nmz_result(self, normaliz_cone, property) 193 PythonModule("PyNormaliz", spkg="pynormaliz").require() 194 import PyNormaliz > 195 return self._nmz_result(normaliz_cone, property) 196 197 def _init_from_normaliz_cone(self, normaliz_cone): RuntimeError: maximum recursion depth exceeded in cmpA function that only calls itself will definitely infinitely recurse.
;)
Additionally, a couple of little details noted by the patchbot from pyflakes for
backend_normaliz.py
:In
def _cone_generators(pynormaliz_cone):
, you havereturn self._nmz_result(pynormaliz_cone, "Generators")In particular,
self
is not been defined in this@staticmethod
.Do you require the
import PyNormaliz
here in_nmz_result
:PythonModule("PyNormaliz", spkg="pynormaliz").require() import PyNormaliz return self._nmz_result(normaliz_cone, property)

I love those...

Is now fixed.
Do you require the
import PyNormaliz
here in_nmz_result
:PythonModule("PyNormaliz", spkg="pynormaliz").require() import PyNormaliz return self._nmz_result(normaliz_cone, property)
This was the cause of the infinite recursion. It is now fixed.

Hm. Annoying.
I can reproduce this with optional=4ti2,bliss,dochtml,e_antic,gfortran,latte_int,lidia,lrslib,memlimit,mpir,ninja_build,python2,sage,topcom
and all tests pass with pynormaliz
added. Dammit.

Got it! It's from a previous test... That's a easy fix. I forgot to put both latte_it and pynormaliz as optional...
