Simulation.Aivika.Parameter

Tested with: GHC 8.0.1

The module defines the Parameter monad that allows representing the model parameters. For example, they can be used when running the Monte-Carlo simulation.

In general, this monad is very useful for representing a computation which is external relative to the model itself.

runParameters :: Parameter a -> Specs -> Int -> [IO a]

Run the given number of parameters using the specified specs, where each parameter is distinguished by its index parameterIndex.

Error Handling

catchParameter :: Exception e => Parameter a -> (e -> Parameter a) -> Parameter a

Exception handling within Parameter computations.

finallyParameter :: Parameter a -> Parameter b -> Parameter a

Predefined Parameters

simulationIndex :: Parameter Int

Return the run index for the current simulation.

simulationCount :: Parameter Int

Return the number of simulations currently run.

simulationSpecs :: Parameter Specs

Return the simulation specs.

generatorParameter :: Parameter Generator

Return the random number generator for the simulation run.

starttime :: Parameter Double

Computation that returns the start simulation time.

stoptime :: Parameter Double

Computation that returns the final simulation time.

dt :: Parameter Double

Computation that returns the integration time step.

Memoization

memoParameter :: Parameter a -> IO (Parameter a)

Memoize the Parameter computation, always returning the same value within a simulation run. However, the value will be recalculated for other simulation runs. Also it is thread-safe when different simulation runs are executed in parallel on physically different operating system threads.

Utilities

tableParameter :: Array Int a -> Parameter a

Return a parameter which value is taken consequently from the specified table based on the run index of the current simulation starting from zero. After all values from the table are used, it takes again the first value of the table, then the second one and so on.
