## 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 )
| inline explicit

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 | ( |  | ) |
| override virtual

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 | ) |
| override virtual

Does nothing in this logger.

Inherited via LaLogger.

Parameters

  [in] | results | scores of the evaluation.

Reimplemented from Log::LALogger.

## ◆ logAfterPopulateTPG()

void Log::CycleDetectionLALogger::logAfterPopulateTPG | ( |  | ) |
| override virtual

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

Inherited via LALogger.

Reimplemented from Log::LALogger.

## ◆ logAfterValidate()

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

Logs the min, avg and max score of the generation.

Inherited via LaLogger.

If doValidation is true, no eval results are logged so that the logger can only show validation results.

Parameters

  [in] | results | scores of the validation.

Reimplemented from Log::LALogger.

## ◆ logEndOfTraining()

void Log::CycleDetectionLALogger::logEndOfTraining | ( |  | ) |
| override virtual

Inherited via LaLogger

Reimplemented from Log::LALogger.

## ◆ logHeader()

void Log::CycleDetectionLALogger::logHeader | ( |  | ) |
| override virtual

Does nothing in this logger.

Inherited via LALogger
