Member Function Documentation

virtual void QFunctionForFactoredDecPOMDP::ComputeWithCachedQValues ( bool  computeIfNotCached )

inlinevirtual

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.

Implements QFunctionInterface.

string QFunctionForFactoredDecPOMDP::GetCacheFilename ( ) const

virtual

Gets the filename where the Qvalues should be stored.

Implements QFunctionInterface.
