Member Function Documentation

virtual ObservationModelMappingSparse* ObservationModelMappingSparse::Clone ( ) const

inlinevirtual

Returns a pointer to a copy of this class.

Implements ObservationModelDiscrete.

References ObservationModelMappingSparse().

double ObservationModelMappingSparse::Get ( Index  ja_i, Index  suc_s_i, Index  jo_i  ) const

inlinevirtual

Returns P(jo|ja,s')

Implements ObservationModelDiscreteInterface.

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

inline

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

Referenced by TransitionObservationIndependentMADPDiscrete::CreateCentralizedObservationTransitionModel(), and AlphaVectorPlanning::Initialize().

void ObservationModelMappingSparse::Set ( Index  ja_i, Index  suc_s_i, Index  jo_i, double  prob  )

inlinevirtual

Sets P(o|ja,s')

jo_i, Index ja_i, Index suc_s_i, are indices of the joint observation, taken joint action and resulting successor state. prob is the probability. The order of events is ja, s', o, so is the arg. list
