Course description

This is an introduction to graph theory. There will be emphasis both on proof and algorithmic techniques. Topics include tours and graphs, planarity, graph colouring, trees, shortest paths, flows, matchings.  Prerequisite is Math 340.

Text

Robin J Wilson, Introduction to Graph Theory, Pearson. ISBN-13: 978-0-273-72889-4.  Other books on the subject can also be found in the library around QA 166.

Homework

There will be a weekly homework assignment due on Thursdays at the start of class. The homework is the most important part of the course as most of your learning will take place while doing it.   We will not accept late homework except in very unusual circumstances. We will, however, drop the lowest homework grade.

Exams

Midterm, Tuesday 10th February.
Final exam, TBA.

Calculators, books, notes etc are not permitted in either exam. Please bring your student ID to both exams.

Please note that there are no make-up or alternate exams, so make sure you do not make travel plans, work plans etc that will conflict. Valid documentation must be provided within 72 hrs if any consideration is to be taken for a missed midterm.

Grading

Your grade will be based on the homework (10%), the midterm (30 or 40%), and the final (60 or 50%), whichever gives you the best grade.

Since this is a Mathematics Majors course, there is a median grade of around 68% and students will be expected to perform calculations and construct rigorous proofs involving fundamental ideas of the course.

Working together and academic integrity

Homework: We have no objection to collaboration on the homework, provided that it is done in a way that maximizes the benefit of the homework to all people involved. It is our experience that you get Regardless of whether you arrive at solutions in collaboration with others or alone, the paper that you turn in with your name on it should represent your own solutions, written in your own words.

In particular, you may not simply copy someone else's homework and turn it in as your own. Similarly, copying solutions that you might find on the web or from some other source is illegal.

These will all be treated as a violation of UBC's Academic Integrity Code. We take academic integrity very seriously and will follow university procedures in all cases of suspected cheating - disciplinary measures can result in expulsion.

Exams: There is anecdotal evidence that quite a bit of cheating occurs on campus. In an effort to prevent one common form of cheating, we will xerox a random sample of exam books before returning them.

Class etiquette

Use of cell phones (in any manner), laptops, smartphones, tablets and other electronic devices during class is highly inappropriate, as it is distracting and disrespectful to fellow students and the instructor. Chatting with neighbours, even when whispered, is equally inappropriate. If you have a question then please ask the instructor so the whole class may benefit too.

Arriving late and leaving early is also discouraged. If it happens then please enter/leave the room silently and do not disrupt the other students or instructor. Thank you.
