Known Subclasses:
  - AbstractNCMCPropagator
  - , HMCPropagator
  - , RWMCPropagator

Provides the interface for MC trajectory generators. Implementations generate a sequence of states according to some implementation of AbstractSingleChainMC.

Nested Classes
Inherited from `AbstractPropagator`: `__metaclass__`

Instance Methods

AbstractPropagationResult |
generate(self, init_state, length, return_trajectory=True) Generate a trajectory, starting from an initial state with a certain length. | source code

Method Details

### __init__(self, pdf, temperature=1.0) (Constructor) | source code
x.__init__(...) initializes x; see help(type(x)) for signature Parameters: `pdf` (AbstractDensity) - PDF to sample from `temperature` (float) - See documentation of AbstractSingleChainMC Overrides: object.__init__ (inherited documentation)

### generate(self, init_state, length, return_trajectory=True) | source code
Generate a trajectory, starting from an initial state with a certain length. Parameters: `init_state` - Initial state from which to propagate `length` - Length of the trajectory (in integration steps or stochastic moves) `return_trajectory` - Return complete Trajectory instead of the initial and final states only (PropagationResult) Returns: AbstractPropagationResult Overrides: AbstractPropagator.generate (inherited documentation)

Property Details

### acceptance_rate Acceptance rate of the MC sampler that generated the trajectory. Get Method: unreachable.acceptance_rate(self) - Acceptance rate of the MC sampler that generated the trajectory.
