Book "Compendium of optimization problems. Theory . Examples. Tasks" by Alexeyev V. M. , Galeev E. M. and Tikhomirov V. M. is a unique tool that will become an indispensable assistant for students, graduate students and anyone interested in mathematical optimization In this collection, the authors have collected not only theoretical foundations, but also practical tasks that will help the reader to better understand and master this important area of knowledge. Optimization is not just a mathematical discipline, but a key tool that is used in a variety of fields: from economics and engineering to logistics and project management. The book examines various methods and approaches to solving optimization problems, ranging from classical methods of linear programming to more modern approaches, such as genetic algorithms and gradient descent methods. Each section of the book is illustrated with examples, which allows the reader not only to assimilate the theoretical material, but also to see its practical application. Who is suitable for this collection? First of all, it will be useful for students of technical and economic specialties who study courses in mathematics, statistics and optimization . Also, the book will be of interest to graduate students and teachers who are looking for quality tasks for their classes. But not only the academic audience will find valuable information in this collection . Practitioners working in the field of data analysis, project management or algorithm development will be able to use the presented tasks to improve their skills and expand their professional horizons. The topics raised in the book cover a wide range of issues related to optimization. The authors not only explain the theoretical aspects, but also focus on practical problems that may arise in real life. This makes the book especially valuable for those who want not only to learn the theory, but also to learn how to apply it in practice. An important aspect is that the collection includes tasks of varying complexity, which allows the reader to gradually delve into the topic and master increasingly complex concepts. The style of the authors is distinguished by clarity and accessibility of the presentation . They are able to explain complex things in simple language, which makes the book understandable even for those who are just beginning to get acquainted with the world of optimization. Alexeyev, Galeev and Tikhomirov are experienced teachers and researchers whose work has already proven itself in scientific circles. Their previous publications also deal with various aspects of mathematics and applied sciences, which confirms their high level of expertise. If you are looking for books on mathematical optimization, linear programming or optimization problems, this collection will be a great addition to your library. Not only will it help you prepare for exams, but it will also give you a deeper understanding of how to apply theoretical knowledge to real-world tasks. Readers interested in works such as "
