Shelves: informatica , math Molti problemi matematici possono anche essere considerati "problemi informatici". In definitiva, risolvere il problema significa trovare un algoritmo tale che anche lo stupido computer possa risolverlo. Algorithmic puzzles that have a defined procedure for solving problems. It has a short tutorial section and the rest are problems to solve. Not going to lie, the problems are very challenging even the easy ones. Mar 06, Heather Gray rated it it was amazing A very entertaining book which exercises your algorithmic thinking muscles.

Anany Levitin and Maria Levitin The only puzzle book to focus on algorithmic puzzles Interprets puzzle solutions as illustrations of general methods of algorithmic problem solving Contains a tutorial explaining the main ideas of algorithm design and analysis for a general reader Algorithmic Puzzles Anany Levitin and Maria Levitin Description Algorithmic puzzles are puzzles involving well-defined procedures for solving problems.
The first part of this book is a tutorial on algorithm design strategies and analysis techniques. Algorithm design strategies — exhaustive search, backtracking, divide-and-conquer and a few others — are general approaches to designing step-by-step instructions for solving problems. Analysis techniques are methods for investigating such procedures to answer questions about the ultimate result of the procedure or how many steps are executed before the procedure stops.
The discussion is an elementary level, with puzzle examples, and requires neither programming nor mathematics beyond a secondary school level.
Thus, the tutorial provides a gentle and entertaining introduction to main ideas in high-level algorithmic problem solving. The second and main part of the book contains puzzles, from centuries-old classics to newcomers often asked during job interviews at computing, engineering, and financial companies.
The puzzles are divided into three groups by their difficulty levels. The first fifty puzzles in the Easier Puzzles section require only middle school mathematics. The sixty puzzle of average difficulty and forty harder puzzles require just high school mathematics plus a few topics such as binary numbers and simple recurrences, which are reviewed in the tutorial. All the puzzles are provided with hints, detailed solutions, and brief comments.
The comments deal with the puzzle origins and design or analysis techniques used in the solution. The book should be of interest to puzzle lovers, students and teachers of algorithm courses, and persons expecting to be given puzzles during job interviews.
