Figure 2From: Numerical treatment of stochastic heroin epidemic model(a) In drug users’ fraction Euler–Maruyama converges to drug-present equilibrium, while deterministic solution is the mean of Euler–Maruyama solution for \(\mathrm{h}=0.01\). (b) In drug users’ fraction Euler–Maruyama shows negativity and divergence for drug-present equilibrium for \(\mathrm{h}=4\)Back to article page
