Are graph algorithms used in the kernel?

[Mayuresh Kathe]

Hello,

I found a book-set called "Algorithms in C" by Robert Sedgewick.
It is a 2 volume bundle which is also sold as individual books.

The first volume talks about regular algorithms and data-structures, 
while the second volume is exclusively dedicated to Graph algorithms.

The language and tone of the book is very approachable, and all sample 
code is in C.

Suppose I wish to work "only" at the kernel level of FreeBSD, would I 
have any use of knowledge of Graph algorithms?
If not, I can be productive even by purchasing only the first volume, 
would save me money.

Thank you,
