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. |

Thus , A , always expands at least as many nodes as does the more informed Ag
. We prove this result using induction on the depth of a node in the A , search tree
at termination . First , we prove that if A , expands a node n having zero depth in ...

We elect to prove this subgoal by proving C2 while having available ( only for use
on C2 and its descendant subgoals ) the B - rule ( A → C1 ) . ( This manner of
treating an implicational goal was discussed earlier . Now , however , rather than

We could prove that Clyde was gray only if we could not prove that he was any
other color . However , we could prove that he was another color , namely , white
