This book is a fundamental work on combinatorial analysis and graph theory. Throughout the book runs a three-level structure: it starts with a problem from everyday life to be solved step- by-step, together with the reader. Then the concepts directly associated with the given problem are explained in an understandable way. Finally it offers new, a bit more difficult problems to the reader, who – already having the necessary mathematical background – can solve these. The solutions are given at the end of the book.
