Struct Mixture 

Source 
pub struct Mixture<W, M>(/* private fields */)
where
    W: AliasableWeight;
Expand description

Combines multiple moves into a single mixture

Mixtures are constructed from tuples of (Move, Weight) pairs.

For each step, a single move is selected to determine the next proposal. The probability of selecting a given move is determined by its relative weight.

let move_ = Mixture::from((
    (Stretch::default(), 2),
    (RandomGaussian::new(1.0e-3), 1),
));

let (chain, accepted) = sample(&model, &move_, walkers, MinChainLen(100_000), Serial);
