I'm confused, did you maybe not list one of the ones you were thinking of? In your original post you just list Convex Optimization and then two books on discrete optimization. I'd be very curious to know what the other one you're referring to alongside Convex Optimization.

He said "your #1", making reference to the first book in OPs list: "Numerical Optimization" by Jorge Nocedal and Stephen J. Wright.

It's pretty fun to read.
