}Expand description
Parallel tempering (replica exchange) MCMC
Runs multiple chains at different temperatures to improve mixing and exploration of multimodal distributions.
Fields§
§temperatures: Array1<f64>Temperature ladder
stepsize: f64Base sampler for each chain
swap_interval: usizeNumber of steps between swap attempts
seed: Option<u64>Random seed
