In any case, this is my first major programming "assignment" out of the book. A basic environment simulator to house a simple reflex agent. A simple reflex agent is the simplest approach to AI one can take- look at the world around me and decide on an action to take. Simple reflex, because it doesn't have any memory, or take any steps to model the world. It just looks around and does something. It doesn't have any ability to formulate goals or even find an optimal path to its desired goal.
It's an interesting bit of Prolog code, and it really shows off many of the major features of the language. Heavy use of recursion, tail-call optimizations, and even a prolog-esque approach to making it vaguely object oriented. Lists, some basic IO calls. The whole kit-n-kaboodle.
I'm kinda proud of it, largely because this lays a decent enough framework for a lot of the future exercises from my AI book.
