About the course
The course consists of three hours of lectures and and three hours
of exercise classes each week, throughout the third quarter (first
half of spring semester). The exam is a graded three hour written exam,
Each student must hand in satisfactory
solutions to three compulsory assignments in order to take the
exam. They should be completed individually (in Danish or English), but
disucssions on the assignments are allowed and encouraged.
The solutions should be given to the teaching assistant in person
at specific exercise classes. If you passed the compulsory program
in the course of 2005-2008, it can be transferred to this course,
but please send me an email to Peter Bro Miltersen requesting
such a transfer as
early as possible and before March 1. Please let the subject
header of the email be "dOpt: Transfer".
Tutorials
Tutorials will start the first week of the semester (Jan 25).
The classes can be found here.
The Monday class is run by Rasmus Ibsen-Jensen (rij@cs.au.dk).
The Tuesday class is directed by Rocio Santillan (rocio@cs.au.dk).
The Wednesday class is commanded by Morten Schaumburg (u033306@cs.au.dk).
You can switch classes if and only if you can find somebody to switch
with.
Compulsory assignments
- Compulsory Assignment 1, hand in at the third tutorial: Solve Problem 2 of the exam of August
2008. There is a misprint in the statement of the problem. In case
of a tie, both teams get one point.
- Compulsory Assignment 2, hand in at the fifth tutorial: Solve Problem 1 of the exam of August
2008 (Originally, by an unfortunate error, the assignment was stated to be Problem 1 of the exam of March 2008. So, if you already prepared or started to prepare the solution to this problem, it is okay to hand this in instead.
But Problem 1 of August 2008 makes better training.)
- Compulsory Assignemnt 3, hand in at seventh tutorial: Solve
Problem 3 of the exam of August
2008.
