Martial Arts Sudoku Level 9: Black Belt Sudoku Review

Average Reviews:

(More customer reviews)I enjoy the toughest Sudokus, I do solve them all; when really at a 'dead-end', I rely on "Ariadne's thread", aka 'smart-guessing' (once I have narrowed down dozens of relations). This book drives me to that process more than any other, including more often than with Frank Longo's other good book "Second-Degree Black Belt Sudoku".

Sudoku fever is on! Which book in the Martial Arts Sudoku series will provide the perfect challenge for you? The skill level recommended to solve these puzzles is ranked in the same way as Japanese karate levels—by different colored belts. Easy sudokus bore you, but The Black Belt collection never will. It's the ultimate thrill for pros like you.

Recursively Enumerable Sets and Degrees: A Study of Computable Functions and Computably Generated Sets (Perspectives in Mathematical Logic) Review

Average Reviews:

(More customer reviews)This text was specifically written to replace Rogers as the standard graduate introduction. As you will see if you ask around, it wasn't completely successful. That is because, while Rogers is creaking with age, it is interesting. This book is not. It is a detailed and orderly presentation of what the author thinks is important, but that does not include any context, motivation, relations to other math, or applications. It is painfully dull. (There is a 2e in the works, but the excerpts I saw were about the same.) Also, it starts very fast and will be confusing if you haven't already done a book like Cutland. I think the problem is that he has been a master of the subject for so long that he can't put himself in the mind of someone coming to the material for the first time.

The first part consists of an introduction to the theory of computation and recursive function theory, including definitions of computable functions, Turing machines, partial recursive functions, recursively enumerable sets, the Kleene recursion theorem etc. The second part is a comprehensive study of recursively enumerable sets and their degrees.

Second-Degree Brown Belt Sudoku (Martial Arts Sudoku) Review

Average Reviews:

(More customer reviews)This was the first sudoku book I bought after doing numerous puzzles from newspapers and online. This book lasted me a good 6 months, and was an excellent time killer on bus cummutes to work, during lunch breaks, during a hospital stay, while waiting for food in restaurant, and anywhere else the sudoku mood struck me.
The puzzles can not simply be solved by inspection. You must fill in all of the cells with number possibilities. Some of the puzzles can easily be solved by single candidate from there, while others require you to use candidate reduction strategies.
A good book to start with for anyone serious about getting into sudokus.
