Member Function Documentation

virtual void BayesianGameForDecPOMDPStageInterface::ClearAllImmediateRewards ( )

pure virtual

We can also clear this cache.

Implemented in BayesianGameForDecPOMDPStage.

virtual void BayesianGameForDecPOMDPStageInterface::ComputeAllImmediateRewards ( const FactoredDecPOMDPDiscreteInterface *  fd )

pure virtual

When performing a lot of GetImmediateReward calls we can first compute a cache of immediate rewards, to speed things up.

Implemented in BayesianGameForDecPOMDPStage.

virtual double BayesianGameForDecPOMDPStageInterface::ComputeDiscountedImmediateRewardForJPol ( const boost::shared_ptr< JointPolicyDiscretePure > &  jpolBG, const PlanningUnitFactoredDecPOMDPDiscrete *  pu  ) const

pure virtual

Compute the discounted expected imm reward for jpolBG.

Implemented in BayesianGameForDecPOMDPStage.

virtual double BayesianGameForDecPOMDPStageInterface::GetImmediateReward ( Index  jtI, Index  jaI, const FactoredDecPOMDPDiscreteInterface *  fd  ) const

pure virtual

Returns the (expected) immediate reward for jtI, jaI.
