I have posted solutions to thursday's exercises in the "timeplan". Some of the exercises were a bit longer and more difficult than previous ones. You can aks me questions about them in the zoom session I will have again on thursday from 1315-1400 (zoomlink below). On thursday, feel also free to ask questions about the first compulsory exercise.

I have just published the first compulsory exercise here. I can answer questions about this on the weekly zoom-meetings we have on thursdays. I have also published tuesday's lecture in the "timeplan": Teaching will be digital next week as well.

If any of you are interested in forming study groups, to discuss the curriculum or exercises with other students, I suggest that you show up at thursday's zoom session (see previous message) or write to me by email, so that I can help to connect interested students. This may be a good idea if you struggle working things out on your own all the time, in this (digital) time of the pandemic.

Thursday 1315-1400 I have another zoom meeting where you can ask questions from the book or the exercises. I will this meeting every thursday at the same time, as long as teaching is digital only. Zoomlink follows below.

I think I now have resolved the sound issue from some of my lectures, so that the sound in upcoming lectures should be better. Thursday's recording of the exercise session has been published with improved sound.

I will publish the first compulsory exercise within the next week.

The lecture plan has now bee updated for the rest of the semester.

I will be available for questions between 1315 and 1400 today, as I did last week. zoomlink follows below.

The sound in my last recordings hasn't been that good: The microphone in my headset stopped working, so that I only had access to the built-in microphone in my computer, which doesn't eliminate background noise. I hope this issues is fixed from next thursday' recording.

The recording for tuesday's lecture has already been posted. This concerns mostly chapter 6 in the book. This material may seem rather technical, as a procedure involving many formuals is developed. The standard dictionary approach is much simpler to apply by hand in that formulas need not be remembered. It is just important to notice that the two procedures perform the same tasks and pivots.

I have now published exercises for several more weeks in the "timeplan". If you want to stay ahead, you may also want to look at "a mini-introduction to convexity", which we will get to in a couple of weeks. You can find a link to this under teaching resources, or if you  log into leganto under "pensum/litteraturliste".

The next lectures will continue to be digital only, but I hope some of the restrictions can be lifted within a couple of weeks. I have posted a recording for next tuesday's lecture already. I plan to add a recording for next week's exercise session shortly.

Since the lectures so far have been recordings only, I have set up a zoom session tomorrow (thursday) between 1315 og 1400 where you can ask questions. zoomlink follows below. We also need a "tillitsvalgt" for the course, and maybe I can discuss this with some of you in tomorrow's zoom session.

You may also be interested in the "fellesorakel", where it is possible to ask general questions. The link for this is https://www.mn.uio.no/math/studier/ressurser/fellesorakel/

Next week's lectures can now be found in the "timeplan". Since the lectures seem to be digital for quite some time still, I will set up a zoom-meeting some time next week, so that you also can ask me questions. I will post a message about this on the course webpage soon.

A recording for thursday's exercise session can now be found in the "timeplan". Regarding tomorrow's lecture, don't be scared about the proof that Bland's rule does not cycle: This is very technical, and not suitable as an exam question. 

Note also that I have put out a file where you can run several of the exercises for this week using the simplex1-implementation of the simplex method (exercises_week3). I have also improved and documented simplex1. I will wait translating this to Python to when we come to the point where we make the simplex method more robust (chapter 6).

It has been decided that next week's lectures will be digital as well. I have therefore posted today a recording of tuesday's lecture (chapter 3). It is a bit longer than 90 minutes, since I also went through the proof that Blands rule prevents cycling (this is rather technical, and difficult to fint into 90 minutes).

Under code on the course web page you also find some code I use in the lecture, and which verifies the computations in some of the examples.

Over the weeked I will also post a recording of thursday's exercise session. I hope you try to solve the exercises before you watch that recording.

Note that you can also find old solutions to exercises and lecture notes in pdf, under old lecture notes on the course web page.

It has been decided that the lectures next week also will be digital only. I will again post recordings as I did this week, and put them on the course webpage (at monday latest).

Due to the pandemic situastion, all lectures next week will be digital only. I have therefore made recordings for tuesday's and thursday's lecture already. Video and pdf can be found in the "timeplan".

I hope we can have lectures in the auditorium as soon as possible.

Welcome to MAT3100! The first lecture will be on 12th January, and we will be in aud. 5 VB (see the calendar). Hopefully there will be no restrictions on meeting up for the lectures, but due to the ongoing corona pandemic all lectures will also be made available as recordings. I will also use zoom so that the lectues can also be followed live. 

The syllabus has been updated (we use leganto), as well as the calendar. In addition, the lecture notes are also part of the syllabus, and will be made available continuously.

We will use the fifth edition of Vanderbei's book. I believe it will cause no problem if you already have the fourth edition.
