Member Function Documentation

virtual TransitionModelMappingSparse* TransitionModelMappingSparse::Clone ( ) const

inlinevirtual

Returns a pointer to a copy of this class.

Implements TransitionModelDiscrete.

References TransitionModelMappingSparse().

double TransitionModelMappingSparse::Get ( Index  sI, Index  jaI, Index  sucSI  ) const

inlinevirtual

Returns P(s'|s,ja).

Implements TransitionModelDiscreteInterface.

const SparseMatrix* TransitionModelMappingSparse::GetMatrixPtr ( Index  a ) const

inline

Get a pointer to a transition matrix for a particular action.

Referenced by TransitionObservationIndependentMADPDiscrete::CreateCentralizedSparseTransitionModel(), AlphaVectorPlanning::Initialize(), and MDPValueIteration::Plan().

void TransitionModelMappingSparse::Set ( Index  sI, Index  jaI, Index  sucSI, double  prob  )

inlinevirtual

Sets P(s'|s,ja)

sI, jaI, sucSI, are indices of the state, taken joint action and resulting successor state. prob is the probability. The order of events is s, ja, s', so is the arg. list

Implements TransitionModelDiscreteInterface.
