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). This package is the spiritual successor to the GillespieSSA package originally written by Mario Pineda-Krch.

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()).
