Description copied from interface: ExplanationGenerator

Returns a single explanation for the given unsatisfiable class.

Specified by:

getExplanation in interface ExplanationGenerator

Parameters:

unsatClass - The class that is unsatisfiable for which an explanation will be generated.

Returns:

A single explanation for the given unsatisfiable class, or empty set if the concept is satisfiable
