Today's assignment
Social structure. Read Preface, p. 1, and sections 1.1 to 1.3.2. Graph theory exercise due (distributed by email) - submit answers via the Moodle (see above for instructions regarding network diagrams). Brainstorm some MCSN examples with research questions.

Graph theory (Wilson ch. 1)
- vertex
- edge,arc
- degree
- graph, digraph
- multiple edges, loops
- simple graph
- walk (alternating sequence of connected vertices and lines)
- path (alternating sequence of connected vertices and lines, such that the vertices don't repeat)
- Eulerian graph (contains a walk containing every edge once, and returning to starting point)
- Hamiltonian graph (contains a walk containing every vertex once, and returning to starting point)
- connected and disconnected graphs
- tree (only one path between each pair of vertices)
- planar graph
- counting graphs
- isomorphic graphs, and difference
- how many different simple graphs can you create with a fixed number of vertices? (1,2,3,4)
- Wilson ch.1 questions
ESNAP reading
- Sections 1.1 to 1.3.2.
