The bottom-up approach

Usually, when a system is built or studied, there are two main approaches: top-down and bottom-up. The former starts from the high-level structures of the system and proceeds gradually into the granular details of the system. The latter starts from the basics and proceeds to create more complex structures that depend on the previous ones. Both approaches are valid, but, as a matter of preference, I chose the bottom-up approach to introduce the topics of this book.

In fact, we will start with how an agent can move, then understand how it can perceive, and finally use this data to make an informative decision or even come up with a plan. This is reflected in the structure of this book and its parts.
