Grading: Homeworks: 20%, Midterm: 20%, Final: 60%.

Difficulty: This is an introductory course in Graph Theory and related topics. The students are expected to learn the theory and solve problems on the homeworks. The problems will be both computational and require some proof abilities.

Other expectations: I would guess that the average student should spend about 8-10 hours per week outside of class to get a decent grade. Much of this time should be spent on the homeworks, but some should be spent on reading the book and absorbing the class material.


We will cover most book sections covering Graph Theory. Although much of the material will follow the textbook, I will change the order of sections and some additional material will be presented in class, so class participation is very important. More specific info on the order of sections will be posted soon.

Home Assignments

The weekly home assignments will be given on Wednesdays to be returned also on Wednesdays. No assignment will be given over the week before the midterm. Worst HA will be dropped from the final score. The assignments will be posted here (on the course web page) in .pdf format. Unless announced otherwise, you need to return them in writing right before the Wed class. No late assignments will be accepted.

Midterm: Wed May 4, 2016, in class. Midterm problems.
Answers: 1. 252, 9!/2, 448, 10, 0, 2. 56, 3. V=12, E=30, F=20, see Icosahedron, 5. FTTTF TTFFF.

Final: Mon June 6, 2016, 3:00-6:00 pm

Collaboration Policy

For the homeworks, you can form discussion groups of up to 4 people each. In fact, I would like to encourage you to do that. You can discuss problems but have to write your own separate solutions. You should write the list of people in you group on top of each HW.
