Theory of optimal solutions?

Question

Search Engine Optimization

Good afternoon, Habr!
What books do you know on the theory of optimal solutions? I know that there is a section devoted to this in the book by Menkov and Ostreikovskiy "Theoretical Foundations of Automation", but a significant drawback of the available information is the complete absence of identification names of the described algorithms for finding optimal solutions. What would you advise to do in this case?
Thank you for your reply.
Sincerely, heinehen.
