Discrete Mathematics . Basics of graph theory" under the authorship of N. A. Bogulskaya and the team of authors is an exciting and deep dive into the world of discrete mathematics, which will become an indispensable assistant for students, graduate students and anyone interested in this exciting field of science. This work not only illuminates the basic concepts of graph theory, but also offers readers a unique perspective on the application of this knowledge in various fields - from computer science to social networks. Graph theory is one of the most important sections of discrete mathematics, which studies graphs as mathematical structures consisting of nodes and connecting their edges. The book discusses basic concepts such as vertices, edges, paths, cycles, and connectivity components. But do not think that this is only a dry theory .. The authors masterfully present the material, making it accessible and understandable, even for those who are just beginning to get acquainted with mathematics. Each section is filled with examples, tasks and illustrations, which allows the reader not only to assimilate information, but also to apply it in practice. The book will be of interest to students of technical and mathematical specialties, as well as to anyone who wants to deepen their knowledge in the field of algorithms and data structures. It will be an excellent addition to the training materials for those who study computer science, programming and related disciplines. If you are interested in mathematical puzzles or want to know how graphs can help solve real problems, this book will be a real discovery for you. The topics raised in the book are diverse and relevant. The authors discuss not only theoretical aspects, but also the practical application of graph theory in various fields: from network optimization and routing to the analysis of social interactions. Readers will be able to learn about important concepts such as the Dijkstra algorithm, minimum spanning trees, and planar graphs. This knowledge will help not only in studies, but also in professional activities, since the ability to work with graphs is in demand in many modern professions. Style N. A. Bogulskaya and her colleagues are distinguished by the clarity and logic of the presentation . The authors strive to make complex mathematical concepts available to a wide audience, which makes the book not only a textbook, but also a fascinating reader. In addition to the main material, the book presents tasks of varying complexity, which will allow readers to test their knowledge and skills.
