Here are suggested solutions to the practice exam
I will be available on Friday* June 7th from 13:00 - 15:00 in NHA Room 1119 to answer any questions about the curriculum, homework problems, previous final exams and this year's practice exam. If you have questions, send them to me in advance and they can be prioritised.
The room is book from 12:00 and you are welcome to meet with others for a group study session before hand.
*The original message read Thursday June 7th (which does exist). If you cannot meet Friday but planned to come today, please get in touch and we can set up another meeting in person or on zoom.
A practice exam is here
* There was a mistake corrected in Problem 3.3 in the polynomial g_1(x). It now reads g_1(x) = x^4 + x^2 + x +1.
The Abel lectures are held today until 15:00. Our review lecture will start at 15:15.
Since there is a large gap between the end of the semester and our final exam, I have offered to schedule a review session and possible group study sessions during week 23 (June 3-7th and possibly the 10th)

If there is enough interest multiple sessions may be scheduled, so be sure to fill out the poll if you will find this helpful. A time and location will be posted once there are enough answers to the poll.
Below is a list of topics that will be covered on the final exam together with the corresponding sections of the textbook and indications of additional course notes (when a topic is not covered in the book). All textbook material that is on the exam is also covered in the PDF course notes if you do not have a copy of Aigner.
Please get in touch if there is anything you are wondering about or if you need help finding the relevant notes for a specific topic.
PART I Counting
Fundamentals and counting coefficients
Binomial coefficients, k-permutations, partitions, compositions, permutations
(Text book sections: 1.1, 1.2, 1.3, 1.4)

Here are some proposed solutions to the obligatory assignment.
Your results and comments are uploaded to canvas. Please get in touch if you have any problems accessing them or math questions. You can either book a meeting by email or come to office hours Wednesdays between 11.00 and 12.00 NHA 1116.
This week's exercise session is unfortunately cancelled due to illness. There are exercises posted and they will be covered in the first session after easter on the 4th of April.

There have been some slight changes to the course schedule.
Thursday March 14th - exercise session will be covered by myself (Kris). Please send an email if you plan on attending (krisshaw@math.uio.no) as it is right before the oblig submission deadline.
Monday March 18th - Lecture on the traveling salesperson problem will be covered by Kristian Ranestad. This will also be a chance for graph theory Q&A.
Wednesday March 20th - Lecture cancelled
All of this information is updated in the course time table.
Since Thursday's exercise session is right before the obligatory assignment submission deadline, send me an email if you plan on coming (krisshaw@math.uio.no). If I receive no confirmation I will cancel the session.
I will be covering Thursday's exercise session this week due to illness.
The obligatory assignment is due on Thursday March 14th at 14:30 in Canvas.
If you would like feedback on a draft, you can send it to me by email prior to the deadline. Feedback is guaranteed for drafts sent before the 8th of March. After that it will depend on time and volume.
If you will writing your solutions in latex the source file can also be helpful.
Get in touch with questions or for help!
Your student representative is Emil Skille?s
Thanks Emil for volunteering!
The problems list was shortened to give more time for the obligatory assignment (the exercise about the "dual matroid" was removed).
Here is a nice text of Keith Conrad explaining Stirling's formula for the asymptotics of n! and some applications.
https://kconrad.math.uconn.edu/blurbs/analysis/stirling.pdf
updated version corrected typos in the hint of problem 5.1 and in the formula for m_1 in 5.4.
We will start with counting Q&A in Monday's lecture. Please send all Q&A questions to me via email: krisshaw@math.uio.no
If we don't have enough time to take up the questions live in the lectures, you will receive an answer in another form (PDF, office hours, etc) .
