Basics of discrete mathematics and algorithm theory: a workshop for students of the specialty "Inform. Systems and Technologies in Economics by Sergey Alexandrovich Pottosin is a unique publication that will become an indispensable assistant for students studying computer science and related disciplines. This workshop offers readers not only the theoretical knowledge but also the practical skills necessary to successfully master the basics of discrete mathematics and algorithmic thinking. In the first part of the book, the author examines in detail the key concepts of discrete mathematics, such as logic, sets, functions, and relationships. Pottosin explains how these fundamental elements bind to algorithms and how they are applied to real-world problems. He emphasizes the importance of understanding these fundamentals for future information technology professionals, emphasizing that without a strong foundation in discrete mathematics, it is impossible to effectively solve complex problems arising in programming and software development. The book pays special attention to algorithms - their structure, types and methods of analysis. Pottosin does not just list algorithms, but immerses the reader in the process of their creation and optimization. Each section is accompanied by practical tasks that help to consolidate the knowledge gained and put it into practice. This makes the book especially useful for students who want not only to learn the theory, but also to learn how to apply it in real projects. Who can like this edition? First of all, it will be useful for university students studying in specialties related to computer science, programming and information technologies . However, you should not limit yourself to this audience .. The book will also be of interest to teachers who are looking for quality materials to prepare their classes, as well as to anyone who wants to deepen their knowledge in the field of discrete mathematics and algorithms. The topics raised in the book cover a wide range of issues, from the basics of logic to complex algorithmic structures. Pottosin focuses on how discrete mathematics permeates all aspects of information technology and how it helps in solving practical problems. Readers will be able to see how algorithms affect software performance and how choosing the right algorithm can significantly improve system performance. The author's style is distinguished by clarity and accessibility, which makes the material easy to perceive. Pottosin uses a variety of examples and tasks, which allows readers to better understand and assimilate complex concepts. Its previous edition, Algorithms and Data Structures, also received positive reviews for its practical focus and accessible language. Basics of discrete mathematics and algorithm theory: a workshop for students of the specialty "Inform. Systems and Technologies in Economics" is not just a textbook, but a full-fledged guide to the world of algorithms and discrete mathematics. It inspires study and research, opens new horizons in the understanding of information technologies and their application in economics. If you are looking for a quality and practical guide on these topics, this edition will be a real find for you.
