By Anany Levitin, Maria Levitin

Whereas many contemplate algorithms as particular to desktop technology, at its center algorithmic pondering is outlined via analytical good judgment to resolve difficulties. This good judgment extends a long way past the world of laptop technology and into the huge and enjoyable global of puzzles. In Algorithmic Puzzles, Anany and Maria Levitin use many vintage brainteasers in addition to more recent examples from task interviews with significant businesses to teach readers the best way to practice analytical considering to resolve puzzles requiring well-defined procedures.

The book's certain selection of puzzles is supplemented with conscientiously constructed tutorials on set of rules layout options and research thoughts meant to stroll the reader step by step in the course of the a variety of methods to algorithmic challenge fixing. Mastery of those strategies--exhaustive seek, backtracking, and divide-and-conquer, between others--will reduction the reader in fixing not just the puzzles contained during this booklet, but in addition others encountered in interviews, puzzle collections, and all through daily life. all the a hundred and fifty puzzles includes tricks and suggestions, in addition to remark at the puzzle's origins and resolution equipment.

The purely ebook of its sort, Algorithmic Puzzles homes puzzles for all ability degrees. Readers with purely center college arithmetic will enhance their algorithmic problem-solving talents via puzzles on the user-friendly point, whereas pro puzzle solvers will benefit from the problem of pondering via more challenging puzzles.

Sample text

All of the coins in one of these stacks are counterfeit, and all the coins in the other stacks are genuine. Every genuine coin weighs 10 grams, and every fake weighs 11 grams. You have an analytical scale that can determine the exact weight of any number of coins. What is the minimum number of weighings needed to identify the stack with the fake coins? 12. Questionable Tiling Is it possible to tile an 8 × 8 board with dominoes (2 × 1 tiles) so that no two dominoes form a 2 × 2 square? 13. 3. No path can cross the fenced off area shown in grey in the figure.

This method is sometimes called the incremental approach. For a specific example, see the first solution of the Rectangle Dissection puzzle (#3) in the book’s main section. Divide-and-Conquer The divide-and-conquer strategy is to partition a problem into several smaller subproblems (usually of the same or related type and ideally of about the same 2 x , called the ceiling of a real number x, is the smallest integer larger than or equal to x. 3 = 3 and 2 = 2. x , called the floor of x, is the largest integer smaller than or equal to x.

For such examples, see 2n-Counters Problem (#37) and Straight Tromino Tiling (#78) in the main section of the book. One more comment needs to be made about the divide-and-conquer strategy. Although some people consider decrease-and-conquer (discussed above) as a special case of divide-and-conquer, it is better to consider it as distinct design strategy. The crucial difference between the two lies in the number of smaller subproblems that need to be solved on each step: several in divide-and-conquer algorithms, and just one in decrease-and-conquer algorithms.
