Graf theory in entertaining tasks. More than 250 tasks with detailed solutions. 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 in students, facilitates the assimilation of computing technology. For a successful solution to most tasks proposed in this book, knowledge in mathematics in the volume of high school is enough.

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 recommendation lists for schoolchildren, teachers, as well as for students.
