Probability distribution via Gillespie SSA a Error of the probability distribution obtained form a SSA-generated trajectory is plotted versus number of steps. The upper axis indicates cpu-time. The vertical bands represent switching of the two-stable system. b The level lines of the probability distribution recovered by analysing frequency of a single SSA trajectory visiting each of the states followed by smoothing with a rectangular 3×3 window. c x-coordinate of a single SSA trajectory plotted versus number of steps demonstrates the switching nature of the stochastic system. d Error as a function of CPU-time for the SSA and the approximation
