# Assignment Solutions - Lecture Update - Theory

23/05/15 10:55

Guys,

updated information is available online. The Lecture page has now links to the assignment solutions and individual lecture pages have been updated.

To some of you I recommend additional training on the theory part. For this we discussed setting up additional meet-ups to go over things like bifurcations,

stability analysis etc.

Here’s a doodle poll for possible dates. Those of you who are interested in getting more secure on the topics sign up.

# Scores on Theory Test

21/05/15 11:12

Guys,

just finished grading the test. 17 people took the test. The mean score is 73/100. There’s a clear

devide between a group of people who now have a solid understanding of the concepts and the methods

and those who need a bit more time and assistance because the concepts are new. If you belong to

that group: no worries. At the end of the course you will also understand the stuff and think it’s very easy.

I’ll talk to you guys tomorrow and we will fix a time for a special session which I recommend you attend.

Also, there’s a change of plans for tomorrow. I was asked to go over the third problem set because some

of you had problems with it. So, I will do that first. After that I will show you a presentation video to show you how to

give presentations. This will be entertaining and will be on a topic that we will talk about in class. This video

is intended for you to learn how to give talks which will be important for your seminar presentation. So attend tomorrow.

As a consequence you will

not have to bring your laptop tomorrow

# Todays Test and Friday

20/05/15 21:43

Guys,

I just posted the solutions to today’s theory test (A pdf can also be found on the Lecture page). I’ve looked over your tests and will grade them today. From my first scan I gather that you have done well on average. I will return the graded tests to you on Friday along with homework assignment 3.

Two of you didn’t write down your name on the test. This is not so good. So, if you remember that you didn’t write down your name, let me know.

On Friday, we will do our second Introduction to netlogo session. So, it is vital that you bring your laptops like last Friday.

# Netlogo Crash Course 2

19/05/15 10:21

Guys,

Friday this week (22.5.) we will continue our netlogo crash course. Please bring your laptops with you on Friday. I will provide power supply.

Last time we did “turtles”, on Friday we will do patches. Please review the coding we did last time, so we can continue where we left off.

For tomorrow, I wish you the best of luck. Just printed out the test. All you will need is a pen.

Also: The Seminar talks will begin next week with a presentation by Tom Altenburg and Benjamin Beuster.

Remember that prior to each presentation we need to schedule an individual appointment to discuss your presentation. This is to your own

benefit and will be you the opportunity to get some feedback from me.

# Theory Test

18/05/15 08:47

Guys,

just a quick update on the theory test on Wednesday:

The test is set up. There will be 4 problems covering the topics

1.) qualitative analysis of 1d dynamical systems, finding fixpoints, analyzing their stability, etc.

2.) Bifurcations in 1d systems. Different types of bifurcations, saddle node, transcritical, pitchforc bifurcations

3.) 2d dynamical systems, phase portraits, null-clines, fixpoints, stability, types of fixpoints, Jacobian, etc

Let me know if you have any questions.

The test will start at 8:30 sharp and you’ll have time until 10am. also sharp. Likely you’ll be finished earlier.

With you test score you will be able to earn bonus credits that will count towards your score of the final Klausur.

# Lecture 6 Information and Network Examples

14/05/15 09:26

Guys,

just uploaded the information that goes along with Lecture 6. This includes a script that I used for a networks course I taught in the past. Also the motivational slides as well as links to the different networks we discussed in class. Go to the Lecture 6 page and investigate. I also updated the Lectures page.

Guys,

The seminar page has been updated. We have fewer slots than talks, so we needed to extend two slots my 30 minutes to have three talks.

“long sessions”.

**Herr Bierbrauer**and**Herr Beuster**who are essentially responsible for this because they picked a talk too late, agreed to bring home made cookies or cake to these“long sessions”.

# Seminar Dates for Talks

10/05/15 17:38

Guys,

according to the papers you’ve picked for your presentation I designed a presentation schedule that roughly follows the topics in the lecture. Please have a look on the seminar page.

Presentations will start on May 29th and will end on July 17th.

We will have two presentations during each seminar. Each presentation will be 30 minutes plus 10 minutes discussion.

Before your presentation each one of you needs to schedule a meeting with me twice so we can go over what you will present and how you will present your paper.

Let me know if you have any questions.
