A mapping from parent/decision values to observed utilities. This is output by a DecisionAlgorithm.
Get the specified number of nearest neighbors of the parent value.
Get the specified number of nearest neighbors of the parent value. Returns a tuple list of (distance to parent, decision value, weighted utility).
Get the size of the index.
Abstract base class for indices used to retrieve nearest neighbors in an approximate decision strategy.
