with contributions from Nalin Chhibber, Ernest Davis, Nicholas J. Hay, Jared Moore, Alex Rudnick, Mehran Sahami, Xiaocheng Mesut Yang, and Albert Yu This solution manual is intended for the instructor of a class. Students should use the online site for exercises at aimacode.github.io/aima-exercises. That site is open for anyone to use. It offers solutions for some but not all of the exercises; an instructor can check there to see which ones have solutions. The exercises are online rather than in the textbook itself because (a) the textbook is long enough as is, and (b) we wanted to be able to update the exercises frequently
