Method Details

defaultOptions

public static SolverOptions defaultOptions()

analyze

protected abstract SolverResult analyze(int it,
 int e)

converged

protected abstract boolean converged(int it)

finish

protected abstract void finish()

getEnsembleAvg

protected abstract AvgTable getEnsembleAvg()

getNumberOfModels

public int getNumberOfModels()

isStochastic

public boolean isStochastic()

An ensemble solver is stochastic if any of its submodel solvers is stochastic. Each submodel solver classifies itself, including from the method it resolved at runtime.

Overrides:

isStochastic in class Solver

Returns:

true if any submodel solver returns stochastic estimates

getSolver

public NetworkSolver getSolver(int e)

Returns the child solver associated with sub-model (stage) e.

Parameters:

e - the sub-model index (0-based)

Returns:

the NetworkSolver solving sub-model e

getStageResult

public SolverResult getStageResult(int e)

Returns the latest per-stage SolverResult for sub-model e, as held by its child solver (or null if not yet solved).

Parameters:

e - the sub-model index (0-based)

Returns:

the per-stage solver result
