The text is now complete, except possibly for one more case study to be added to Chapter 16. An
index still needs to be added. Please send any errors to rich@richsutton.com and barto@cs.umass.edu.
We are also very interested in correcting any important omissions in the Bibliographical and Historical
Remarks" at the end of each chapter. If you think of something that really should have been cited,
please let us know and we can try to get it corrected before the nal version is printed.
