WebNov 15, 2024 · Graph burning is a process that models the spread of social contagion [4], [12]. It is a discrete-time deterministic process. Suppose G is a simple finite graph. Initially, every vertex of G is unburned. At the beginning of every round t ≥ 1, a burning source is placed at an unburned vertex, turning its status to burned.
