Magic squares are among the more popular mathematical recreations. Over the last 50 years, many generalizations of âmagicâ ideas have been applied to graphs. Recently there has been a resurgence of interest in âmagic labelingsâ due to a number of results that have applications to the problem of decomposing graphs into trees. Key features of this second edition include: ·        a new chapter on magic labeling of directed graphs ·        applications of theorems from graph theory and interesting counting arguments ·        new research problems and exercises covering a range of difficulties ·        a fully updated bibliography and index This concise, self-contained exposition is unique in its focus on the theory of magic graphs/labelings. It may serve as a graduate or advanced undergraduate text for courses in mathematics or computer science, and as reference for the researcher.
