Detailed Description

Interface for tuning strategies for the auto tuner.

Member Function Documentation

addEvidence()

virtual void autopas::TuningStrategyInterface::addEvidence ( const Configuration &  configuration, const Evidence &  evidence  )

inlinevirtual

Notifies the strategy about empirically collected information for the given configuration.

All evidence is stored centrally in the AutoTuner and its EvidenceCollection is passed to the tuning strategies during optimization.

Implementing this function is only necessary if the tuning strategy processes evidence differently than EvidenceCollection.

Parameters

configuration	Configuration used to obtain the evidence.
evidence	Measurement and when it was taken.

Reimplemented in autopas::ActiveHarmony, autopas::BayesianClusterSearch, autopas::BayesianSearch, autopas::FuzzyTuning, autopas::PredictiveTuning, autopas::RandomSearch, autopas::RuleBasedTuning, and autopas::TuningStrategyLogger.

getOptionType()

virtual TuningStrategyOption autopas::TuningStrategyInterface::getOptionType ( ) const

pure virtual

Get this object's associated TuningStrategyOption type.

Returns

TuningStrategyOption

Implemented in autopas::ActiveHarmony, autopas::BayesianClusterSearch, autopas::BayesianSearch, autopas::FuzzyTuning, autopas::MPIParallelizedStrategy, autopas::PredictiveTuning, autopas::RandomSearch, autopas::RuleBasedTuning, autopas::SlowConfigFilter, autopas::SortByName, and autopas::TuningStrategyLogger.

needsLiveInfo()

virtual bool autopas::TuningStrategyInterface::needsLiveInfo ( ) const

inlinevirtual

Returns whether this tuning strategy wants to get a LiveInfo object passed before a new tuning phase.

Returns

True, if this tuning strategy wants a LiveInfo object passed before a new tuning phase via receiveLiveInfo().

Reimplemented in autopas::FuzzyTuning, autopas::RuleBasedTuning, and autopas::TuningStrategyLogger.

needsSmoothedHomogeneityAndMaxDensity()

virtual bool autopas::TuningStrategyInterface::needsSmoothedHomogeneityAndMaxDensity ( ) const

inlinevirtual

Indicate whether the strategy needs smoothed values of homogeneity and max density.

Returns

Reimplemented in autopas::ActiveHarmony, autopas::BayesianClusterSearch, autopas::BayesianSearch, and autopas::MPIParallelizedStrategy.

optimizeSuggestions()

virtual bool autopas::TuningStrategyInterface::optimizeSuggestions ( std::vector< Configuration > &  configQueue, const EvidenceCollection &  evidenceCollection  )

pure virtual

Optimizes the queue of configurations to process.

This function is called once before each iteration in a tuning phase so all tuning strategies can give their input on which configuration to try next. This is done by reordering configQueue so that the next configuration to try is at the end (FIFO).

Parameters

configQueue	Queue of configurations to be tested. The tuning strategy should edit this queue.
evidenceCollection	All collected evidence until now.

Returns

boolean value to signal if the tuning strategy has intentionally wiped the config queue

Implemented in autopas::ActiveHarmony, autopas::BayesianClusterSearch, autopas::BayesianSearch, autopas::FuzzyTuning, autopas::MPIParallelizedStrategy, autopas::PredictiveTuning, autopas::RandomSearch, autopas::RuleBasedTuning, autopas::SlowConfigFilter, autopas::SortByName, and autopas::TuningStrategyLogger.

receiveLiveInfo()

virtual void autopas::TuningStrategyInterface::receiveLiveInfo ( const LiveInfo &  info )

inlinevirtual

Virtual method that subclasses can override to receive the LiveInfo object before a tuning phase if they return true in needsLiveInfo().

Parameters

info	A new LiveInfo object that has already gathered its information.

Reimplemented in autopas::RuleBasedTuning, autopas::TuningStrategyLogger, and autopas::FuzzyTuning.

receiveSmoothedHomogeneityAndMaxDensity()

virtual void autopas::TuningStrategyInterface::receiveSmoothedHomogeneityAndMaxDensity ( double  homogeneity, double  maxDensity  )

inlinevirtual

Method to pass smoothed homogeneity and the maximal density to the tuning strategy.

Parameters

homogeneity
maxDensity

Reimplemented in autopas::MPIParallelizedStrategy.

rejectConfiguration()

virtual void autopas::TuningStrategyInterface::rejectConfiguration ( const Configuration &  configuration, bool  indefinitely  )

inlinevirtual

Notify the strategy about a configuration that is (currently) invalid and thus can potentially be dropped from some internal storage.

Parameters

configuration
indefinitely	Whether the given configuration will never be valid

Reimplemented in autopas::BayesianClusterSearch, autopas::BayesianSearch, autopas::MPIParallelizedStrategy, and autopas::PredictiveTuning.

reset()

virtual bool autopas::TuningStrategyInterface::reset ( size_t  iteration, size_t  tuningPhase, std::vector< Configuration > &  configQueue, const autopas::EvidenceCollection &  evidenceCollection  )

pure virtual

Reset all internal parameters to the beginning of a new tuning phase.

This can also mean to reorder the configQueue to some initially expected state.

Parameters

iteration	Gives the current iteration to the tuning strategy.
tuningPhase	Gives the current tuning phase to the tuning strategy.
configQueue	Queue of configurations to be tested. The tuning strategy should edit this queue.
evidenceCollection	All collected evidence until now.

Returns

boolean value to signal if the tuning strategy has intentionally wiped the config queue

Implemented in autopas::ActiveHarmony, autopas::BayesianClusterSearch, autopas::BayesianSearch, autopas::FuzzyTuning, autopas::MPIParallelizedStrategy, autopas::PredictiveTuning, autopas::RuleBasedTuning, autopas::TuningStrategyLogger, autopas::SlowConfigFilter, autopas::SortByName, and autopas::RandomSearch.
