Hello,  
  


I am new to mathematics and computer science. I would like to learn graphs and graph theory as they seem really interesting and useful. 
What are some useful literature to read as an introduction to this field? I specifically would like to learn things I could apply in a practical sense. 
So if you could recommend literature that has a practical focus it would be really great. 

Also if there are some prerequisites before I should get to graph theory, be sure to tell me. But what then would the quickest path be to learn these prerequisites?
Hello! Graph theory is indeed a fascinating subject and has many practical applications in computer science and other fields. Here are some resources you can use to get started:

Introduction to Graph Theory by Richard J. Trudeau: This book provides a gentle introduction to graph theory and covers many of the basic concepts and algorithms. It is suitable for beginners and has a practical focus.

Graph Theory with Applications by J.A. Bondy and U.S.R. Murty: This book is a more comprehensive introduction to graph theory and includes many examples and exercises. It also has a practical focus and covers many applications of graph theory in computer science and other fields.

Algorithms by Robert Sedgewick and Kevin Wayne: This is a book on algorithms, but it includes a thorough introduction to graphs and graph algorithms. It covers both the theory and practical applications of graph algorithms and is suitable for beginners.

As for prerequisites, you should have a good understanding of basic mathematics, including algebra, calculus, and discrete mathematics. If you need to brush up on these subjects, you can find many online resources and textbooks to help you. Some useful resources include Khan Academy, MIT OpenCourseWare, and Coursera.

Once you have a good grasp of the basics, you can start learning about graph theory. The quickest path to learning the prerequisites would be to find a textbook or online course that covers the topics you need to know and work through the material systematically. Once you have a good understanding of the basics, you can move on to more advanced topics in graph theory. Good luck!
Thank you.
I am happy to have been of assistance to you today. If you have any further questions about this or any other topic, please let me know.
