This book supplements the textbook of the authors" Lectures on Graph
The- ory" [6] by more than thousand exercises of varying complexity.
The books match each other in their contents, notations, and
terminology. The authors hope that both students and lecturers will find
this book helpful for mastering and verifying the understanding of the
peculiarities of graphs. The exercises are grouped into eleven chapters
and numerous sections accord- ing to the topics of graph theory: paths,
cycles, components, subgraphs, re- constructibility, operations on
graphs, graphs and matrices, trees, independence, matchings, coverings,
connectivity, matroids, planarity, Eulerian and Hamiltonian graphs,
degree sequences, colorings, digraphs, hypergraphs. Each section starts
with main definitions and brief theoretical discussions. They constitute
a minimal background, just a reminder, for solving the exercises. the
presented facts and a more extended exposition may be found in Proofs of
the mentioned textbook of the authors, as well as in many other books in
graph theory. Most exercises are supplied with answers and hints. In
many cases complete solutions are given. At the end of the book you may
find the index of terms and the glossary of notations. The
"Bibliography" list refers only to the books used by the authors during
the preparation of the exercisebook. Clearly, it mentions only a
fraction of available books in graph theory. The invention of the
authors was also driven by numerous journal articles, which are
impossible to list here.
