The algorithm determines how computers process information and how they carry out the task. Efficient algorithm is not only a personal computer to enable you to run the latest generation of gaming with features unimaginable only a few years ago, they are also key to several scientific breakthroughs recently? for example, the human genome sequence will not be possible without the discovery of new algorithm ideas that accelerate the computation by several fold. The biggest improvement in the algorithm relies on ideas that are beautiful to handle computing tasks more efficiently. Most of the article emerged from an initiative between German universities to communicate the attractiveness of algorithms and computer science for high school students. This book can be understood without prior knowledge of algorithms and computation, and will be enjoyable and enlightening reading for students and interested adults.
