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 Intelligence evolved 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. |

For example , the fact expression : ( u ) ( Vv ) { Q ( v , u ) ^ ~ [ R ( v ) V P ( v ) ] ^ S (
u , v ) } } is converted to Q ( v , A ) ^ { [ ~ R ( v ) 1 ~ P ( v ) ] V ~ S ( A , v ) ] } .
Variables can be renamed so that the same variable does not occur in different (

Our explanation of the appropriateness of this operation is dual to the
explanation for applying an F - rule to a fact AND / OR graph . The assertional
rule WL can be negated and added ( disjunctively ) to the goal wff . The negated
form is ( W 1 ...

We note that pruning the AND / OR graphs by detecting inconsistent substitutions
may be impossible in systems that use both B - rules and F - rules because , for
these , both the fact and goal graphs change dynamically , making it impossible ...
