GillespieSSA2: Gillespie’s Stochastic Simulation Algorithm for impatient people.

GillespieSSA2 is a fast, scalable, and versatile framework for simulating large systems with Gillespie’s Stochastic Simulation Algorithm (SSA) (Cannoodt et al. 2021). This package is the spiritual successor to the GillespieSSA package originally written by Mario Pineda-Krch (Pineda-Krch 2008).

GillespieSSA2 has the following added benefits:

The SSA methods currently implemented are: Exact (ssa_exact()), Explicit tau-leaping (ssa_etl()), and the Binomial tau-leaping (ssa_btl()).
