I would like to know which books are best to study integer programming. I can see similar questions on this website, such as this one: Books for integer and mixed integer programming
Integer and Combinatorial Optimization by Nemhauser and Wolsey is one of the recommended books. I am trying to determine whether it is worth getting this book, but I prefer something which is not too heavy with proofs or math symbols. This book was published in 1988 so it will not cover any recent developments. Is this book highly regarded because it provides loads of examples or any material that is not found in the other books?
