This is a book about graph homomorphisms. Graph theory is now an established discipline but the study of graph homomorphisms has only recently begun to gain wide acceptance and interest. The subject gives a useful perspective in areas such as graph reconstruction, products, fractional and circular colorings, and has applications in complexity theory, artificial intelligence, telecommunication, and, most recently, statistical physics.
Based on the authors' lecture notes for graduate courses, this book can be used as a textbook for a second course in graph theory at 4th year or master's...

This volume constitutes the proceedings of the International Conference on Algorithmic Aspects in Information and Management, AAIM 2014, held in Vancouver, BC, Canada, in July 2014.

The 30 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 45 submissions. The topics cover most areas in discrete algorithms and their applications.
