Algorithms for Planar Graphs (Summer 2015)

+++ News +++

registration to the LSF should now be possible

A planar graph is a graph that can be drawn in the plane such that two edges only cross in a common end vertex. In this lecture we will discuss how to exploit properties of planar graphs in order to solve problems more efficiently than on general graphs.

General Information

Lecture (S. Cornelsen) Mon 11:45-13:15 (M 630)
Tutorial Wed 15:15-16:45 - fortnightly (F 429)
Exams 1st date: 13th of July 2015 in PZ 1006
2nd date: 29th of September 2015 in PZ 1006, please sign into the list in PZ 1002

Please register for this course in the StudIS and LSF.


The assignments are made available on this webpage as a PDF-file (in English) every Monday after the lecture.

The editing time for each homework is almost one week.

We will return the corrected and scored assignments fortnightly in the tutorial.

The requirements for the admittance to the final exam are 50 percent of the total score of the assignments and regular attendance at the tutorials. In writing up your assignments, be as clear, precise, and concise as possible. Understandability will be an important factor in the scoring of the assignments. Regular attendance is considered especially for borderline cases.

You are permitted and encouraged to work in groups of two.
