Member Function Documentation

virtual void QFunctionInterface::Compute ( )

pure virtual

Compute the heuristic.

Implemented in QAV< P >, QAV< PerseusBGPlanner >, QAV< PerseusBGNSPlanner >, QAV< PerseusPOMDPPlanner >, QHybrid, QFunctionJAOHTree, QMDP, QAlphaVector, FactoredQLastTimeStepOrElse, FactoredQLastTimeStepOrQBG, FactoredQLastTimeStepOrQMDP, FactoredQLastTimeStepOrQPOMDP, QMonahanBG, QMonahanPOMDP, and QTreeIncPruneBG.

virtual void QFunctionInterface::ComputeWithCachedQValues ( bool computeIfNotCached = true )

pure virtual

Compute Qvalue function, while caching the Qvalues to disk.

Before computing them, the function checks whether the Qvalues have been computed before, and if so, loads them from disk. If not, it computes them, and afterwards saves them for re-use. This behavior can be changed by settings computeIfNotCached to false, in which case an Exception will be thrown if the Q function has not been previously stored on disk.

Implemented in QFunctionForFactoredDecPOMDP, QHybrid, QFunctionJAOH, and QFunctionJointBelief.

virtual std::string QFunctionInterface::GetCacheFilename ( ) const

pure virtual

Gets the filename where the Qvalues should be stored.

Implemented in QFunctionForFactoredDecPOMDP, and QFunctionForDecPOMDP.

Referenced by ArgumentUtils::GetHybridQheuristicFromArgs(), Load(), and Save().

virtual void QFunctionInterface::Load ( )

inlinevirtual

Load the Qvalues from disk.
