Stepsizes over time. Evolution in time of stepsizes of all the stochastic solvers we have compared in the case of the Michaelis-Menten system. The largest steps are taken by the SBS, SBS-DA and unbiased τ-leap, then the θ-trapezoidal τ-leap, and finally the Euler τ-leap. Parameters used were: S1=S2=0.8,atol=10−6,rtol=10−4 for the SBS methods, and ε=0.04,0.1,1 for the Euler, θ-trapezoidal and unbiased τ-leap methods, respectively.
