The book "Discrete mathematics for the engineer", written by well-known experts in the field of mathematics and computer science P. Kuznetsov and G. M. Adelson-Welsky is a unique publication that will become an indispensable assistant for students, graduate students and practicing engineers. This work not only immerses the reader in the world of discrete mathematics, but also demonstrates how these abstract concepts are applicable to real engineering problems. Discrete mathematics is a field that covers a wide range of topics, including graph theory, combinatorics, algorithms, and more. In the book, the authors seek to explain complex mathematical ideas in simple and accessible language, making it ideal for those who are just starting out in this field. Readers will be able to learn how to apply mathematical models to practical problems, which is especially important for future engineers working in areas such as computer science, information technology and system analysis. The book will be of interest not only to students of technical specialties, but also to anyone who wants to deepen their knowledge in mathematics and its applications. If you are interested in programming, developing algorithms or want to understand how mathematics helps in creating effective solutions, this publication will be a real find for you. It is suitable for both self-study and for use in training courses. The topics raised in the book cover key aspects of discrete mathematics, ranging from basics to more complex concepts. The authors emphasize the importance of logical thinking and analysis, which is a necessary skill for any engineer. They share their knowledge of how mathematical models can be used to optimize processes, analyze data, and develop new technologies. This makes the book not only a textbook, but also a practical guide to solving real-world problems. The style of the authors is clear and structured. They use many examples and tasks, which allows the reader to better absorb the material. The book is replete with illustrations and diagrams that help visualize complex concepts. About. P.
