Performs different approaches for network-based source estimation: effective distance median, recursive backtracking, and centrality-based source estimation. Additionally, we provide public transportation network data as well as methods for data preparation, source estimation performance analysis and visualization.
The main function for origin estimation of propagation processes on complex network is
origin. Different methods are available: effective distance median (
'edm'), recursive backtracking (
'backtracking'), and centrality-based source estimation (
For more details on the methodological background, we refer to the corresponding publications.
