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. |

... evaluation function . Evaluation functions have been based on a variety of ideas : Attempts have been made to define the probability that a node is on the best path ; distance or difference metrics between an arbitrary node and the ...
... evaluation function has resulted in substantially fewer nodes being expanded . ( If we simply use the evaluation function f ( n ) = d ( n ) , we get the breadth - first search process . ) The choice of evaluation function critically ...
... evaluation function , we first introduce some helpful notation . Let the function k ( n1 , n , ) give the actual cost of a minimal cost path between two arbitrary nodes n , and n ,. ( The function k is undefined for nodes having no path ...
... function and will discuss it in more detail later . Suppose we now use as an evaluation function f ( n ) = g ( n ) + h ( n ) . We call the GRAPHSEARCH algorithm using this evaluation function for ordering nodes , algorithm A. Note ...
