Welcome to the world of graph theory. Everything you learn here from this moment on will be new to you, just as it has been to
those before you. The reason why I enjoyed this class is because previous knowledge is not necessary. You build your knowledge
from the bottom. New terms will be defined for you. You will be introduced to different types of common graphs. Learn them and
study them. Only then can you easily accept new knowledge and fuse it with your pre-existing one.
In the beginning, you will learn about points and lines, and common families of graphs such as the complete graph, or the wheel
graph, and special graphs like the octahedral graph. In the beginning, there was so much input to remember. But review them over
and over--you will start to learn and recognize them as quickly as they came.
You will be shown proofs for most of the theorems you learn, yet you will be asked to provide some proofs elsewhere. You will
be asked to find statistics on these graphs such as the thickness of a given graph, its chromatic number, and its clique number. I
too was overwhelmed at first, but apply these statistics to graphs. With practice, it will become second nature to you.
The key thing to remember is, "Do not be a passive learner". Those that listen and wait but do not seek, practice, and apply
will not appreciate what they've learned. Instead, they will find themselves frustrated and falling behind. You are here to own
what you learn. Review your notes the same night you wrote them down. Read the related sections in the book to reinforce your
learning. Don't wait until the last moment to complete the homework assignments. Some will take a long time, but you will not
regret how long you've worked on them—your efforts will only help you master your understanding. When you meet with your
group, come prepared to talk about what solutions you've figured out, what progress you've made, or to ask what you didn't
understand.
If there is one thing that this class will never do, it is this: It will never get you bored. The topics contain a wide
variety of interesting questions. With many questions, I have told myself, "Oh, I'm not able to find the solution yet. I'll just
try one more time." Instead, I can't put the question down until I've found the solution. It has become an addiction to answer it,
and I come back thirsty for more. Your enthusiasm for graph theory will grow exponentially by the fun related games to graph
theory such as the Puzzle Loop, the Shikaku, and the Planarity Game, and I am sure you will enjoy the Gale Shapley play on stable
marriages as much as our class had.
As this semester is ending, I have come away with an appreciation for seeing how graph theory is not just points and lines, but
can be seen as a way to describe,finding, and understand the connections between people on the social level and it's applications
on a practical level with events such as transshipment and the assignments of medical schools. So, I wish you all a stimulating,
fun, and successful semester in graph theory and in all your other classes. Best wishes!
Sincerely,
A former graph theory student,
