Diskrete Optimierung/Discrete Optimization

Prof. Dr. Stefan Funke

This lecture takes place twice a week (3 h of lecture and 1 h tutorial) in the following slots:

Day Time Location
Tuesday 11:30-13:00 V38.03
Thursday 09:45-11:15 V38.03

Lecture starts on Tuesday, October 16th.

Possible topics covered in the course

  • Linear Programming
    • Simplex algorithm
    • Duality
    • Linear Programming in fixed dimensions, subexponential Simplex variants
  • Network Flow
    • MaxFlow/MinCut theorem
    • MinCostFlow
  • Approximation Algorithms for NP-hard problems
    • Knapsack, TSP, Set Cover, Hitting Set, …
    • Primal-Dual algorithms
    • Greedy and Dual-Fitting

Also see the introductory slides here (including information about the exams).

There will be a written exam at the end of the semester (unless your Prüfungsordnung does not allow that; in that case, there will be an oral exam).

Scribe Notes

Can be found here (will be updated as the course progresses).

Summary slides with exclusions for the exam are here.

Examination

There will be a test exam handed out in the evening of Feb, 11th; it wil be discussed on Feb 13th, 15:45-17:15. We meet in front of my office 1.111 at 15:45.

Test exam (uploaded Feb 11th)

According to the Prüfungsamt, the exam takes place 11:00-13:00 on March 6th in V38.02!

You need to register in time (before 10.12.2012!) in the LSF for the exam!

Exam results are out! See the board at FMI (1st floor, next to room 1.111).

  • Exam “Einsicht” Friday, Apr 12th, 10:00-12:00, room 1.116.
  • Another Exam “Einsicht”/review will take place May, 2nd, 13:00-13:45; room 1.168.
