### 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
- maximum benefit from a homework problem if you work hard on it
alone
before combining your ideas with someone else's,

- no benefit from one person just telling another how to do a
problem.

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.
