A variant of the Hering illusion

It is important to know that these are books for computer scientists more than for software engineers. They are basically mathematics textbooks, about the mathematics of algorithms. They focus on proving theorems rather than implementing useful algorithms.

There is a book called concrete mathematics that is sort of an introduction to TAOCP. If you’re interested in the basics that may be a good place to start. It has a better title than TAOCP in that it explicitly mentions mathematics, but also an equally bad one because it’s very much theoretical rather than concrete.
