- [1] A graph theory course's lecture notes/psets, uploading by Prof. Dan Spielman of Yale, are free available online. He tends towards spectral graph theory and there is a decent amount of probability involved.
- [2] Discrete Structures by Vladlen Koltun
- [3] Networks, Crowds, and Markets by David Easley and Jon Kleinberg: It combines different scientific perspectives in its approach to understanding networks and behavior. Drawing on ideas from economics, sociology, computing and information science, and applied mathematics, it describes the emerging field of study that is growing at the interface of all these areas, addressing fundamental questions about how the social, economic, and technological worlds are connected.
