Files

• SIR_mapping.m — direct sampling, single realization
• mcmc_sir_meanfield.m — rejection-free Gibbs sampler, mean-field variant
• mcmc_sir_exact.m — rejection-free Gibbs sampler, exact variant with dynamical correlations
• interventions.m — time-critical vaccination strategies (random, hubs, temporal); reproduces Fig. 7

Usage

D = SIR_mapping(A, N, E, beta, gamma, source);
samples = mcmc_sir_meanfield(A, beta, gamma, source, num_samples, burn_in, thin);
samples = mcmc_sir_exact(A, beta, gamma, source, num_samples, burn_in, thin);
