Detailed Description

Detector for connected cycles in TPGs.

This utility class implement a depth-first search algorithm for detecting the presence of directed cyclic paths in TPGs.

Constructor & Destructor Documentation

◆ CycleDetectionLALogger()

Log::CycleDetectionLALogger::CycleDetectionLALogger	(	Learn::LearningAgent &	la,
		std::ostream &	out = std::cerr,
		bool	logOnSuccess = false )

inlineexplicit

Same constructor as LALogger. Default output is cerr.

Parameters

[in]	la	LearningAgent whose TPG will be analyzed by the CycleDetectionLALogger.
[in]	out	The output stream the logger will send elements to.
[in]	logOnSuccess	When true, the logger will log the absence of cycles.

Member Function Documentation

◆ logAfterDecimate()

void Log::CycleDetectionLALogger::logAfterDecimate ( )

overridevirtual

Does nothing in this logger.

Inherited via LaLogger.

Reimplemented from Log::LALogger.

◆ logAfterEvaluate()

void Log::CycleDetectionLALogger::logAfterEvaluate ( std::multimap< std::shared_ptr< Learn::EvaluationResult >, const TPG::TPGVertex * > & results )

overridevirtual

Does nothing in this logger.

Inherited via LaLogger.

Parameters

[in] results scores of the evaluation.

Reimplemented from Log::LALogger.

◆ logAfterPopulateTPG()

void Log::CycleDetectionLALogger::logAfterPopulateTPG ( )

overridevirtual

Checks the presence of directed cyclic path in the TPG. Loggs an output if there is one.
