Book Description
A synopsis of eminent computer chess programs reveal that they are designed around a 'brute force' approach. An argument is made that by continuing the 'brute force' search approach, computer chess development is moving away from human evaluation methods. Research is done into studies of evaluation methods, and a discovery is made that humans use a form of intuition, called their 'sense of beauty', to choose the best chess move. A paper by Margulies is cited which formulates principles of beauty which apply to chess. Three versions of a chess program are developed, using no heuristics, standard chess heuristics, and beauty heuristics formulated from Margulies principles. The performance of the three versions of the program are compared using chess puzzles, and rated for how quickly they find the solution, and how few nodes they evaluate. Graphs are produced from the results of these tests, showing that beauty heuristics are, on average, 15% faster at finding the solution, and evaluate 10% fewer nodes. An improvement is implemented in all versions of the program which biases the search towards better moves, resulting in the beauty heuristics success rising to an average of 25% faster to the solution, and evaluating 33% fewer nodes, than the other heuristics. It is concluded that the beauty heuristics are closer to the way that humans evaluate chess positions.

Book Description
Killer Sudoku (also known as "Sums Sudoku", "Sums Number Place", "Samunamupure", "Kikagaku Nampure") is a mathematical and logical puzzle. About Book This book introduces you to the amazing world of Killer Sudoku puzzles. It will help you understand the rules of this puzzle. This book is perfect for players of all skill levels and ages. You will find 200 exciting puzzles, both for beginners and for professionals. HOW TO PLAY Killer Sudoku is a mix of Sudoku and Kakuro. Your goal is the same as in regular sudoku: fill every row, column and 3x3 region with the numbers 1-9 once. Fill all rows, columns and 3x3 region with numbers exactly like in regular sudoku. Every cell is a part of a cage, indicated by dotted line. Make sure the cells can be added up to the sum of its cage. Numbers cannot repeat within cage. Numbers cannot repeat within a single row, column or 3x3 region. As Killer Sudoku belongs to the same class of puzzles as Sudoku the puzzle can demonstrate a wide spectrum of relative difficulty. The grade is determined by a combination of opportunities to solve at each stage and the difficulty of the strategy that grants each solution. Puzzles almost like Calcudoku, but unlike number cannot appear more than once in a block.
