Read "The Beauty of Algorithms"

1. Where is the fun of algorithms? I
remember that when I first started writing programs, I used the most basic grammar knowledge. At that time, I felt that algorithms were useless. Later, as the work progressed, the project became larger and more time-sensitive. I started to gradually realize the importance of algorithms. The algorithm is so big that it can encompass the running laws of everything in the universe; the algorithm is so small that a few lines of code can show a magical function. The joy of algorithms is everywhere in life. Applications can be seen everywhere in our lives, Wi-Fi at home, smartphones, phones, routers and almost everything with built-in computer systems will use this algorithm in various ways. The man-machine war between AlphGo and Lee Sedol, which has recently been hotly debated on the Internet, was achieved by applying artificial intelligence and machine learning to simulate real scenarios. Although the difference between classical algorithms and machine learning algorithms is as big as a revolution, the process of moving from classics to machine learning is natural. Behind the simplest things, there is the magic behind the algorithm. Algorithms have unknowingly penetrated into our daily lives, reshaping our world. In life, we can apply algorithms to simulate natural systems, and implement various small programs under the natural system like the nature of code. to discover the joy of algorithms.
2. Talk about your opinion on the trial chapters of this
book gives the catalog of the whole book. From the catalog, we can see that the author has classified and summarized the classic algorithms. The sample chapter mainly gives the sixth chapter of the book, which gives an in-depth explanation of the classic recursion problem, including the concept of recursion, the divide-and-conquer method and the backtracking method. A careful reading of this chapter will reveal the difference between this book and other algorithms books, and this book cites some classical literature. It is not boring lectures while telling algorithm knowledge. At the same time, the book gives a simple and easy-to-understand code implementation, and provides a source code download link, which can be easily debugged.
In short, in the era when algorithms have become the cornerstone of computer technology, we must learn to apply algorithms and discover the joy of algorithms.
