Detailed Description

The Last class is a RuleBlock Activation method that activates the last \(n\) rules whose activation degrees are greater than or equal to the given threshold.

The rules are iterated in the reverse order in which they were added to the rule block.

ruleBlock

is the rule block to activate

Implements fl::Activation.

className()

virtual std::string fl::Last::className ( ) const

virtual

Returns the name of the activation method, which is also utilized to register the activation method in the ActivationFactory.

Returns

the name of the activation method
