Graf theory in entertaining tasks. More than 250 tasks with detailed solutions. 9th edition. Melnikov O.I.

The present book in a popular and affordable form sets out the basics of the theory of counts - the division of discrete mathematics, which, having been born in solving puzzles, has currently become a powerful means of solving both theoretical and production problems. The basic concepts in the book are illustrated by examples, and evidence of theorems are consciously built into solving entertaining problems. The book presents more than 250 tasks of various complexity, separated by topics, their solutions are given.

The study of elements of the theory of graphs contributes to the development of mathematical thinking, modeling skills, and facilitates the assimilation of computational technology. For the successful solution of most of the tasks proposed in this book, there is enough knowledge in mathematics in the volume of high school.

The book is intended for schoolchildren and teachers, it can also be useful to students; Tasks from it can be used in preparation for mathematical olympiads of various levels. The publication is included in various advisory lists for schoolchildren, teachers, as well as for students.
