Currently, I am building a book report/reviews in an effort to convince some professors to change their in-class textbooks to free open-access books to reduce the burden of cost unto the students taking their courses, as for example, one of my courses is using this book to teach Deterministic Optimization, and that book costs $\$120$, and there were sizable complaints from students being unable to afford the book for the class. I have found some book lists on this site, but only one answer out of the $20+$ had an open-access, free book. Even with the last couple months of looking around online, I've had no success as I only found one site that had open-access optimization theory resources, and it's rather poor for intro learners. Of course there are sites like this one that promotes book sharing, but the limitations for book accesses limits a whole classroom who are competing with using it as a resource for a single book.
Thus, I am reaching out to here in a request for strictly open-access, or free-online$^{[ 1 ]}$, optimization textbooks that are hard to find or not so widely known about.
The following topics are the ones I am looking for:
- Linear Programming
- Non-Linear Programming
- Network Programming
- Constraint Programming
- MIP/Integer Programming
This is ultimately important to me in that cost shouldn't be a barrier for theses fun courses, and thus there should be alternatives that students can use that doesn't destroy their savings, as most optimization textbooks that are good are quite costly, but I am at an absolute loss on finding more than what I have already found, as it's easier to motivate such a change in the department for such classes if there's more options for them to pick from.
