    Chapter 4 of "The Art of Prolog" ("The Computation Model of Logic Programs") is about that very topic. It doesn't go into gory details on how to optimize an interpreter for fast ex…

    A good book to read to get aquainted with these notions is "Meta Math" by Gregory Chaitin. The impatient can jump to chapter 5. https://arxiv.org/abs/math/0404335
