Resonating bond update.

Required methods

pub fn constant_ops_on_var(&self, var: usize, ps: &mut Vec<usize>)

Fill ps with the p values of constant (Hij=k) ops for a given var. An implementation by the same name is provided for LoopUpdaters

pub fn spin_flips_on_var(&self, var: usize, ps: &mut Vec<usize>)

Fill ps with the p values of spin flips for a given var. An implementation by the same name is provided for LoopUpdaters

Provided methods

pub fn rvb_update<R: Rng, EN: EdgeNavigator, H>(
    &mut self,
    edges: &EN,
    state: &mut [bool],
    updates: usize,
    diagonal_edge_hamiltonian: H,
    rng: &mut R
) -> usize where
    H: Fn(usize, bool, bool) -> f64, 

Perform a resonating bond update. edges lists all the 2-site bonds which define the lattice. state is the propagated state at time 0. updates is the number of updated to perform. diagonal_edge_hamiltonian gives the weight of a diagonal edge given a spin state. rng prng instance to use.

    &mut self,
    edges: &EN,
    state: &mut [bool],

    H: Fn(usize, bool, bool) -> f64,
    F: Fn(&Self::Op) -> f64, 

Perform a resonating bond update. edges lists all the 2-site bonds which define the lattice. state is the propagated state at time 0. updates is the number of updated to perform. diagonal_edge_hamiltonian gives the weight of a diagonal edge given a spin state. ising_ratio provides the weight ratio of a node after a global ising flip to current. rng prng instance to use.
