CHAPTER

The Problem With Forward Chaining

This relates to an algorithm that's used in mathematical optimization, which is the idea of gradient ascent for going up or if you're going down.

Okay, I'll take one little step in that whatever direction goes up the very fastest. Then I'll look around again and figure out now in my new position what little step goes up the fastest. And you can prove that for many types of mountains, so to speak, this algorithm will eventually get you to the top of the mountain.
