  • defaultRuleEvaluationFactoryPtr – An unique pointer to an object of type INonDecomposableRuleEvaluationFactory that should be used for calculating the predictions, as well as corresponding quality scores, of the default rule

  • regularRuleEvaluationFactoryPtr – An unique pointer to an object of type INonDecomposableRuleEvaluationFactory that should be used for calculating the predictions, as well as corresponding quality scores, of all remaining rules

  • pruningRuleEvaluationFactoryPtr – An unique pointer to an object of type INonDecomposableRuleEvaluationFactory that should be used for calculating the predictions, as well as corresponding quality scores, when pruning rules

  • numThreads – The number of CPU threads to be used to calculate the initial statistics in parallel. Must be at least 1
