Red and blue particles are placed in equal proportion throughout either the complete or star graph and iteratively sampled to take simple random walk steps. Mutual annihilation occurs when particles with different colors meet. We compare the time it takes to extinguish every particle to the analogous time in the (simple to analyze) one-type setting. Additionally, we study the effect of asymmetric particle speeds.

完全图和星图上的两种湮灭系统

红色和蓝色粒子在整个完整图或星图中以相等的比例放置，并迭代采样以采取简单的随机游走步骤。当不同颜色的粒子相遇时，就会发生相互湮灭。我们将熄灭每个粒子所需的时间与（易于分析）单一类型设置中的类似时间进行比较。此外，我们研究了非对称粒子速度的影响。
