About the cover: painting by Kathy Emami, entitled "Eve's Cycle." The painting beautifully abstracts concepts discussed in the book: anchored graphs, trees, cycles, weighted edges, interconnected nodes, and nodes (in this case apples) that have (almost) reached agreement on their states (in this case colors and shapes).

We will be posting teaching suggestions, pictures, research questions, slides, video clips, list of typos/clarifications, and additional exercises as they pertain to the book on this site.
