TPSL: A propagation source localization method based on limited observation nodes

The research on locating the sources that initiate a diffusion process on complex networks has far-reaching significance in various fields. In this paper, we propose the multi-source localization method TPSL based on limited observation nodes from the perspectives of infection time and infection probability. Simulations on both the synthetic and empirical networks demonstrate that TPSL has excellent performance. We also explore the influence of...
