Class ScreenedRemainderSets

All Implemented Interfaces:
Serializable, Cloneable, Iterable<Collection<ASPRule>>, Collection<Collection<ASPRule>>, Set<Collection<ASPRule>>

public class ScreenedRemainderSets extends RemainderSets<ASPRule>
This class represents the set of Screened Consistent Remainder Sets as defined in [1]. A screened remainder set X of P regarding a set of sentences R \subseteq P is a set X s.t. (1) R \subseteq X \subseteq P, (2) X is consistent and (3) there is no proper superset X' of X in P that is also consistent.

      public ScreenedRemainderSets(Program p, Program r, ASPSolver solver)
      Creates a new set of screened remainder sets of program p that all contain the screened rules r. An asp-solver is used to calculate the consistency of remainder set candidates.
      p - an asp-program for which the screened remainder sets are calculated
      r - an asp-program representing the set of rules, that have to be contained in every remainder set. Has to be a subset of p
      solver - an asp-solver
