Struct SamplerParams 

pub struct SamplerParams {
    pub burn_in: Option<u64>,
    pub thinning: Option<u64>,
    pub p_do_nothing: f64,
}

Parameters for the MCMC sampler.

Fields

burn_in: Option<u64>

Burn-in steps to reach equilibrium from initial cyclic state.

This is the number of MCMC steps (including do-nothing steps with probability p_do_nothing). The expected number of actual Jacobson-Matthews moves is burn_in * (1 - p_do_nothing).

If None, uses n³ as the burn-in value. The mixing time of Jacobson-Matthews is empirically observed to be O(n³ log n), though not rigorously proven. Using n³ provides good uniformity in practice.

thinning: Option<u64>

Thinning factor: steps between successive samples.

If None, uses 3×n² for approximate independence. Based on ACF analysis, this achieves IACT τ ≤ 1.10 and |ACF(1)| ≤ 0.05 for all n.

p_do_nothing: f64

Probability of doing nothing (for aperiodicity).
