Two of the authors (Korte, Vygen) also wrote a textbook on combinatorial optimization: <a href="https://link.springer.com/book/10.1007/978-3-662-56039-6" rel="nofollow noreferrer">https://link.springer.com/book/10.1007/978-3-662-56039-6</a>. I haven't read it and I don't know enough about the subject to be able to say how useful the algorithms in the book are specifically for VLSI design.
