ArgumentationKnowledgeBase

public ArgumentationKnowledgeBase(Program program)

Constructs an `ArgumentationKnowledgeBase` object initialized with a given program.

Parameters:

program - the `Program` object representing the program to be used for initializing the argumentation knowledge base. The program is cloned internally to avoid modifying the original program.

Throws:

IllegalArgumentException - if any rule in the program has an `AggregateHead` as its conclusion.
