Fast, extensible Python library for simulating epidemic processes on graphs. Implements the Zombie Infection Model (ZIM), SIR model, and provides optimized algorithms for large-scale stochastic simulations. Features exact Gillespie scheduling, specialized lattice implementations, and tools for phase transition analysis. This has been superseded by the Julia library GraphEpimodels.jl that can be found at https://github.com/smodee/GraphEpimodels.jl and will probably not be updated further.
