Chapter 1Mathematical Background
This chapter reviews rudimentary concepts from logic (Section 1.1), set theory (Section 1.2), discrete mathematics (Section 1.3), and graph theory (Section 1.4). For readers familiar with these concepts, this chapter can be treated as a reference for notation and definitions.
