Dear students,

points for all your submitted projects should be in CMS. As for the grading scheme: 1 point was subtracted for every 2 less solved problems in comparison to the reference solution (in cases no reference was available, the best solution was taken as the reference). All submissions with a segmentation fault were graded with zero points. If I found a more serious problem, less points were assigned and I wrote you an email describing where the problem was. As always, if you think you deserve more (or less) points than assigned, or if you want to discuss anything related to your projects, then either come discuss it with me during office hours, or write me an email at danfis@cs.uni-saarland.de.

Best,

As described in the competition sheet, we will have a preliminary test run of the competition tomorrow. If you want your planner to be included in the test run, you need to prepare the submission until tomorrow night (11:59 pm):

Dear students,

this is to update you regarding this question, which you are certainly wondering about.

As of now, the official university regulation is that exams will take place as planned (under Corona hygiene and distancing rules of course; you will receive details regarding those later).

The alternative would be to postpone the 1st exam. This is not possible however within the upcoming term break, as March/April is already booked for all the 2nd exams. So one of the two exams would have to be in fall. This would cause serious issues both for the faculty (finding space and time within the summer term break) and the students (having to re-prepare for a course taken 6 months ago).

So we will proceed as planned.

If you cannot attend the 1st exam for good reasons (abroad and unable to travel/quarantined/acute symptoms) then we will offer you an oral exam. In this case, please write an email to Rebecca Eifler eifler@cs.uni-saarland.de

best regards, and good luck with the upcoming exams under these unfortunate circumstances,

Jörg Hoffmann

Dear Students,

This is a reminder that, in order to take the Planning exam you must register in two different places, until one week before the exam at the latest: February 5.

1) CMS: We have opened the registration in CMS. You'll be able to register as soon as you fulfill the requirements (50 points in programming projects). Of course, we'll try to upload the points as soon as possible so that you can do this early.

2) HISPOS/VIPA: This depends on your course of studies and I don't have the list, but you should know if your course of studies is using one of these. If so, you need to register in the corresponding system. Students in course of studies that belong to HISPOS or VIPA and don't register there will not be allowed to take the exam. If you cannot register in HISPOS or VIPA, please write Rebecca (eifler@cs.uni-saarland.de) once you register in CMS so that we keep track of the list of students that attend the exam without being in HISPOS or VIPA.
For more Information please check this news (18.11.20)

The exam is on the 12. February in HS002 in E1.3. at 10:00.
We will publish further information about the exam with respect to corona rules next week.

Best regards,
Rebecca

Hi all,

just FYI in case it's not clear: (I saw someone in Gather just now who seemed to want to talk to me but then disappeared)

  • I'll be on the stage in the "Lecture Hall" after each lecture.
  • You can actually navigate to any Gather participant by clicking on his/her name on the top right and choosing "locate". This will show you a shortest path to that person.
  • There is no need to come on the stage to talk to me; it is enough to stand within a small radius.
  • Chrome generally works best for Gather.

The programming projects overview is now online (see course material). In this sheet, you will find all the organizational details regarding the projects (repository setup, nightly tests, grading), as well as a short description for each individual subproject and their dependencies.

There will be a programming workshop on Thursday November 12th at 2:15pm (see organization page). In the workshop, we will give you a brief overview of the projects you can choose to implement. We will also give you an introduction to the Fast Downward framework with some live coding to prepare you for the projects (in fact, you might already be able to finish the first project in the workshop). Before the workshop, you should have read the projects overview, and have set up your repository so you can follow the live coding in the workshop.

Please use the forums for general questions about the projects. If you have specific questions about your code, you can come to gather.town during the office hours (Thursdays 10am, see organization page) or send a mail to Dan Fišer (danfis@cs.uni-saarland.de).

Dear students,

we have, after all, decided to provide a central Gather space for the course:

https://gather.town/app/xzOEC0RRMfqoXtGV/FAI

This space serves for the following functionalities:

  1. Lectures, tutorials, and introductory programming workshop wil be in the "Lecture Hall" in the Gather space. Entering that space and pressing 'x' will transfer you to zoom.
  2. The weekly office hours will take place directly in the Gather space, so that students can form groups and tutors can "walk around between" these groups.
  3. The lecturers will be in Gather after the lectures, so you can walk up to them and ask any additional questions you might have.
  4. You may use this space as an online meeting space for students. The Gather space will be always open, and it provides ample space for individual meetings and discussions.

Points 2. and 3. are the reasons for designing the Gather space despite your majority "I don't care" vote in the first lecture. Office hours are more naturally supported in such a space, and the same is true for questions to us after the lecture (of which there were quite a few already). That said, you can still access lectures directly, via the same zoom link as before.

Hope you enjoy the course!

best regards,

Jörg Hoffmann
