Discrete Mathematics . Counts" edited by Y. A. Shitova is a fascinating and deep dive into the world of discrete mathematics, which will become an indispensable assistant for students, graduate students and anyone interested in mathematics and its applications in various fields. This work is not just a textbook, but a real encyclopedia of knowledge about graphs, their properties and applications, which makes it relevant for both beginners and more experienced researchers. The book examines the key concepts and theories associated with graphs - structures consisting of vertices and edges, which are widely used in computer science, biology, sociology and many other sciences. You will be able to learn about different types of graphs, such as oriented, undirected, weighted and unweighted, as well as important concepts such as connectivity, cycles and trees. Each chapter is filled with examples, tasks and illustrations, which makes the material accessible and understandable for perception. Who can like this book? First of all, it will be useful for students of technical and mathematical specialties who study discrete mathematics as part of their curriculum . It will also attract the attention of teachers who want to enrich their classes with new approaches and examples. The book will be equally interesting for specialists working in the field of computer science, as graphs play a key role in algorithms and data structure. Lovers of mathematics and logical problems will also find in it a lot of fascinating and useful. The topics raised in the book cover not only theoretical aspects, but also practical applications of graphs in real life. Readers will be able to learn how graphs are used to model social networks, optimize logistics processes, analyze biological systems, and even develop computer games. These examples make the material more alive and relevant, showing how mathematics can be applied to solve real-world problems. The style of the author and the team of authors is distinguished by clarity and accessibility, which makes it easy to assimilate even the most complex concepts. Yu. A. Shitov is a well-known specialist in mathematics and pedagogy, who has already established himself as the author of a number of textbooks and scientific papers. His approach to teaching and presenting material makes the study of discrete mathematics not only useful, but also a fascinating process. If you are looking for books on discrete mathematics, graphs or algorithms, then "Discrete Mathematics. It will be a great choice..
