Interface BaseContractionOperator<T extends net.sf.tweety.commons.Formula>

  • Type Parameters:
    T - The type of formulas that this operator works on.
    All Known Implementing Classes:
    KernelContractionOperator, MultipleBaseContractionOperator, RandomKernelContractionOperator
    public interface BaseContractionOperator<T extends net.sf.tweety.commons.Formula>
    This is the interface for a classic belief base contraction operator, ie. an operator that takes some set of formulas and a single formula and contracts the former by the latter.
