Grading Policy for VO+PS "Computational Geometry"
- According to the Austrian Universities Act 2002, students have the right
to be examined according to an alternative method if they suffer from a
permanent disability which makes it impossible for them to take an
examination in the prescribed manner and the other method does not limit
the content and standards of the examination.
Hence, if you feel that the requirements outlined below to pass VO+PS
"Computational Geometry" cannot be met by you due to such a disability
then, please, get in touch with the University's
as soon as possible. Please understand that directives of the Rectorate
prevent me from consenting to any bilateral agreements if the
has not been involved!
- VO "Computational Geometry" will be graded on the basis
of oral exams
that take place in my office and that cover the material taught in class.
- PS "Computational Geometry" will be graded as follows:
- Weekly individual assignments have to be worked out by each
- Unless announced explicitly otherwise, after each VO lecture (on Fridays)
I will post a sheet
with new assignments no later than on the subsequent Monday.
- All assigments (given so far) will be available as one
on the webpage of the course.
- All new assignments will be discussed in the PS class
in the week following the post date.
- Hence, in general you will have about one and a half weeks to work
out the assignments. (There might be
exceptions to this rule which I will announce clearly.)
- Please use our
"Abgabesystem" to mark those
assignments which you are willing to present in class. You can enter (or
change) your checkmarks until 01:00 on that Friday on which
the assignments are due.
- Please make sure to register for our
in time. Your "Username" is your student ID number ("Matrikelnummer"), and
you can (re)set your password via email by clicking on "Passwort
zurücksetzen: basierend auf E-Mailadresse". You will then get an
email (in English) with instructions on how to (re)set your PWD.
- Your PS grade will be based on the number of assignments for which
you declared a willingness to present them and on your performance at the
blackboard/whiteboard during the presentation of assignments.
- In addition, I will take notes of other noteworthy contributions of
students during class.
- In order to get a passing grade you are required to mark
at least MIN assignments as the ones which you are willing to present
in class, where MIN is computed as follows:
I expect X to be about(!) 50, and Y to be about 12. Please note that
marking at least MIN assignments is a necessary but not a sufficient
condition for passing the PS!
- Let X be the total number of assignments posted.
- Let Y be the total number of different assignment sheets.
- Let MAX := (X/Y) * (Y-1).
- Then MIN := 0.5 * MAX.
- You can get credit for the assignments
worked out only if you attend the PS personally.
- You are not required
to hand-in your assignments, unless explicitly requested for some
- You may cooperate and discusss the assignments
with other students. (Of course, with the exception of those few
assignments for which I explicitly request everybody to come up with
his/her own solution!)
- Similarly, you are welcome to consult textbooks
or online sources.
- Frankly speaking, I do not care whether or not you
discuss assignments among your peers, or how you come up with a solution.
- However, I will not tolerate plagiarism: Once you mark an assignment
as solved then I expect you to fully understand your solution. That is, if
I ask you to come to the whiteboard and to explain your solution then
you'll have to be able to argue why your solution ought to be
correct, and you have to be able to answer questions concerning
(sub-)problems related to your solution.
- Please note that I
will use the quality of your explanations and arguments at the whiteboard
as a positive or negative weight when determining your final grade. In an
extreme case, this means that marking all X assignments but delivering
very poor explanations whenever I ask you to come to the whiteboard will
still result in failing the PS!
- In any case, if presented with a full
line of arguments then I will be much more lenient towards "solutions"
that fall apart. On the other hand, phrases like "It seems like..." or "I
believe that..." or "This is true!!!" (without any rational why it should
be true) simply do not belong to the line of reasoning employed by
computational geometry, and I will react harshly to such
"solutions". Hopes and fears are an important part of everybody's life,
but computational geometry is not about hopes or fears but about rigorous
- As a rule of thumb, if you are not convinced that you can outline a
full suite of arguments then it is likely smarter not to claim credit for
an assignment and have one assignment less to your credit, than to risk
being caught by me.
- If you'd come up with two or more solutions then
I'd advise you to focus on one solution and work it out in detail, rather
than have several "half-baked" solutions.
- For specific assignments
that are to be handed in in writing I do not allow cooperation since I do
not want to read the same solution several times, once verbatim
identically, once with "I" replaced by "J", once with "I" replaced by "K",
and so on. Part of the reason why I want you to work out written solutions
is that I would like you all to practice writing up solutions. (Clearly,
this goal is not met if one solution would be copied multiple times.)
- As a final remark, let me emphasize that the level of theoretical
difficulty of the contents of the VO and of the PS assignments will be
rather moderate compared to international standards. Take a look at some
of the leading textbooks, or grab assignments posted by colleagues on the
web, and you'll quickly learn that there are far more involved
assignments out there. I appreciate the fact, though, that this type
of work (and the skills required) are set apart from most of the other
classes that you might have attended in your CS (or even math) studies
