- 12. Algorithms: a common language for nature, human, and computer. ” — Avi Wigderson What is an algorithm? Algorithm can be defined as a method for solving a problem. Some people think that it is something new, but the study of algorithms dates at least to Euclid – 300 BC! It was formalized by Church and Alan Turing in 1930s and developed more in the 20th century. It is interesting that some important algorithms were discovered by university students and not by expert programmers! The impact of algorithms is broad and far-reaching. First, the Internet is full of them, for example, the web search, packet routing, and distributed file sharing. Second, the world of biology also works with algorithms: think of human genome project and protein folding. In the 20th century, algorithms contributed to the development of computers with the circuit layout, file system, compilers and many other things. Text Algorithms
- 13. Consequently, computer graphics appeared and introduced movies, video games and virtual reality in our lives. In the 21st century, algorithms have been used for different social networks features like recommendations, news feeds, advertisements, and so on. Did you know that voting machines also use algorithms to count the votes in elections? So they are even used in politics! So why should we study algorithms? They can help us solve problems that cannot have other solutions. If you want to stimulate your intellect and become a proficient programmer, it is also a good idea to study algorithms. Additionally, they may unlock the secrets of life and of the universe. Finally, computational models are replacing math models in scientific inquiry and will become more and more important in the future. Adapted from: Coursera, Algorithms Part I Text Algorithms
