Book Description
Algorithmic puzzles are puzzles involving well-defined procedures for solving problems. This book will provide an enjoyable and accessible introduction to algorithmic puzzles that will develop the reader's algorithmic thinking. 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 150 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.

Book Description
Steam Trains and Jigsaw Puzzles strikes most people as an intriguing title. The origin is simple,however my trainspotting youth has been synchronized with a later interest in jigsaw puzzles. The result is expensive I have a collection of over 250 jigsaws depicting British steam railways. The conclusion is impossible there are over 500 steam railway jigsaw puzzles to collect and they are being supplemented annually. The Liverpool & Manchester Railway marked the arrival of the true passenger railway service in 1830 and presented jigsaw manufacturers with another subject on which to focus. Prior to this date the jigsaw experience, started by John Spilsbury in c1760, was restricted to subjects such as religion, geography, history, monarchs, the alphabet and art. Many characteristics combine to form the basis of nostalgic images buried indelibly in the minds of people who travelled in the steam railway age. Manufacturers have not been slow to tap into this nostalgia and produce jigsaws aimed at stirring those memories and inviting people to reflect on past experiences, good, bad or indifferent. Chad Valley, Victory, Good Companion,Falcon, Waddingtons and Arrow are just a few manufacturers who produced steam railway jigsaws in the past. Most of these companies are now a distant memory while others are in foreign ownership. Equally famous names such as Wentworth, Ravensburger (Germany), House of Puzzles, Gibsons, JR Puzzles and King Puzzles (Holland) continue the manufacturing tradition. Output is generally superb thanks to the efforts of fine railway artists such as Terence Cuneo, George Heiron, T. E. North, Don Breckon, John Austin, Barry Freeman and Malcolm Root. The book is aimed at anyone with an interest in jigsaw puzzles and at those enthusiasts and aficionados who refuse to allow those evocative memories of the Golden Age of Steam to die.

Book Description
This second puzzle eBook contains a collection of 50 puzzles or riddles with their solutions. These brain teasers require insight to solve but not brute force. Some of them rely on common sense. Others are AHA or GOTCHA puzzles that Martin Gardner loved. There are some that rely on lateral thinking while others require convoluted logic to solve. Of interest are some uncommon puzzles such as cross numbers and puzzles extracted from real life situations. When selecting the puzzles, two attempts were made: 1) Not to include commonly available puzzles 2) Not to include puzzles that require general knowledge or expertise in specific domains (such as math or algebra). The intended age bracket is from early teens onwards.

Book Description
You have a choice to rewrite your story of destruction as a story of redemption. In 2013, after a prolonged struggle with shame, public humiliation and vocational crisis, Father Ramadhani was sent for a residential treatment. Working on jigsaw puzzles with fellow residents soon became his new hobby. Little did he know that this would lead him to soul-searching conversations with the images on those puzzles—Golden Gate Bridge, Dubrovnik, Riomaggiore, Sydney Opera House, Big Ben Clock Tower, Castle of Chambord, Mount Rushmore, Portland Head Lighthouse. The result is this smooth blend of Ignatian contemplation and mythic imagination. Tapping on the strength of vulnerability, this book encourages anyone dealing with inner unresolved issues, to pull away, listen, look honestly inside the soul with the eyes of an outsider, and if possible, humbly seek professional help.
