Principles of Artificial IntelligenceA classic introduction to artificial intelligence intended to bridge the gap between theory and practice, Principles of Artificial Intelligence describes fundamental AI ideas that underlie applications such as natural language processing, automatic programming, robotics, machine vision, automatic theorem proving, and intelligent data retrieval. Rather than focusing on the subject matter of the applications, the book is organized around general computational concepts involving the kinds of data structures used, the types of operations performed on the data structures, and the properties of the control strategies used. Principles of Artificial Intelligenceevolved from the author's courses and seminars at Stanford University and University of Massachusetts, Amherst, and is suitable for text use in a senior or graduate AI course, or for individual study. |

Each leads to a different instance of F-rule that can be applied. ... is applied to the
literals in the delete list; and the ground instances thus obtained are deleted from
the old state description as the first step of constructing the new one.

Therefore , if a goal expression contains a literal , L , that unifies with one of the
literals in the add list of an F - rule , then we know that if we produce a state
description that matches appropriate instances of the preconditions of that F - rule
, the ...
