The aim of the book is to introduce programming as a key qualification with numerous application possibilities to engineers or scientists. The author explains algorithmic methods that underpin today's digital products and services. Key applications include artificial intelligence, data mining, predictive analytics, Industry 4.0, and the Internet of Things. Digital data analysis, along with the associated algorithms, forms the central foundation of many new IT technologies. This involves processing large amounts of data from various application fields and analyzing them for specific patterns to extract relevant information. These so-called intelligent methods are the basis for nearly all innovations in our digitized world. Through this type of information processing, new insights are gained by combining mathematics and computer science.
