compare

public abstract ComparisonCriterion.Result compare(DelpArgument argument1,
 DelpArgument argument2,
 DefeasibleLogicProgram context)

This method returns the relation of argument1 to argument2 given context.

Parameters:

argument1 - a DeLP argument

argument2 - a DeLP argument

context - a defeasible logic program as context

Returns:

- Result.IS_BETTER iff argument1 is better than argument2
- Result.IS_WORSE iff argument1 is worse than argument2
- Result.IS_EQUAL iff argument1 and argument2 are in the same equivalence class
- Result.NOT_COMPARABLE iff argument1 and argument2 are not comparable
