Tested with: GHC 7.6.3

The module defines the Simulation monad that represents a simulation run.



data Simulation a Source

A value in the Simulation monad represents something that doesn't change within the simulation run but may change for other runs.

This monad is ideal for representing the external parameters for the model, when the Monte-Carlo simulation is used. Also this monad is useful for defining some actions that should occur only once within the simulation run, for example, setting of the integral with help of recursive equations.

class Monad m => SimulationLift m whereSource

A type class to lift the simulation computations to other monads.


liftSimulation :: Simulation a -> m aSource

Lift the specified Simulation computation to another monad.

runSimulation :: Simulation a -> Specs -> IO aSource

Run the simulation using the specified specs.

runSimulations :: Simulation a -> Specs -> Int -> [IO a]Source

Run the given number of simulations using the specified specs, where each simulation is distinguished by its index simulationIndex.

Error Handling

catchSimulation :: Simulation a -> (IOException -> Simulation a) -> Simulation aSource

Exception handling within Simulation computations.

finallySimulation :: Simulation a -> Simulation b -> Simulation aSource

A computation with finalization part like the finally function.

throwSimulation :: IOException -> Simulation aSource

Like the standard throw function.


simulationIndex :: Simulation IntSource

Return the run index for the current simulation.

simulationCount :: Simulation IntSource

Return the number of simulations currently run.

simulationSpecs :: Simulation SpecsSource

Return the simulation specs.
