Class SeqFloatGreaterEqual

    • Field Detail

      • dkconfig_enabled

        public static boolean dkconfig_enabled
        Boolean. True iff SeqFloatGreaterEqual invariants should be considered.

    • Method Detail

      • enabled

        public boolean enabled()
        Returns whether or not this invariant is enabled.
        Specified by:
        enabled in class Invariant

      • isObviousStatically

        @Pure
public @Nullable DiscardInfo isObviousStatically​(VarInfo[] vis)
        Checks to see if the comparison is obvious statically. Makes the following checks: 
            max(A[]) op A[]
    min(A[]) op A[]
        JHP: Note that these are not strict implications, these are merely uninteresting comparisons (except when op is GreaterEqual for max and LessEqual for min).
        Overrides:
        isObviousStatically in class Invariant
        Parameters:
        vis - the VarInfos this invariant is obvious over. The position and data type of the variables is the *same* as that of this.ppt.var_infos.

      • clone

        @SideEffectFree
public SeqFloatGreaterEqual clone​(@GuardSatisfied SeqFloatGreaterEqual this)
        Description copied from class: Invariant
        Do nothing special, Overridden to remove exception from declaration.
        Overrides:
        clone in class Invariant

      • repr

        public String repr​(@GuardSatisfied SeqFloatGreaterEqual this)
        Description copied from class: Invariant
        For printing invariants, there are two interfaces: repr gives a low-level representation (Invariant.repr_prob() also prints the confidence), and Invariant.format() gives a high-level representation for user output.
        Overrides:
        repr in class Invariant
        Returns:
        a string representation of this

      • format_esc

        public String format_esc​(@GuardSatisfied SeqFloatGreaterEqual this)

      • check_modified

        public InvariantStatus check_modified​(double @Interned [] a,
                                      double x,
                                      int count)
        Description copied from class: SequenceFloat
        Presents a sample to the invariant. Returns whether the sample is consistent with the invariant. Does not change the state of the invariant.
        Specified by:
        check_modified in class SequenceFloat
        count - how many identical samples were observed in a row. For example, three calls to check_modified with a count parameter of 1 is equivalent to one call to check_modified with a count parameter of 3.
        Returns:
        whether or not the sample is consistent with the invariant

      • isExact

        @Pure
public boolean isExact()
        Description copied from class: Invariant
        Subclasses should override. An exact invariant indicates that given all but one variable value, the last one can be computed. (I think that's correct, anyway.) Examples are IntComparison (when only equality is possible), LinearBinary, FunctionUnary. OneOf is treated differently, as an interface. The result of this method does not depend on whether the invariant is justified, destroyed, etc.
        Overrides:
        isExact in class Invariant
        Returns:
        true if any variable value can be computed from all the others

      • isSameFormula

        @Pure
public boolean isSameFormula​(Invariant other)
        Description copied from class: Invariant
        Returns true iff the two invariants represent the same mathematical formula. Does not consider the context such as variable names, confidences, sample counts, value counts, or related quantities. As a rule of thumb, if two invariants format the same, this method returns true. Furthermore, in many cases, if an invariant does not involve computed constants (as "x>c" and "y=ax+b" do for constants a, b, and c), then this method vacuously returns true.
        Specified by:
        isSameFormula in class Invariant
        Parameters:
        other - the invariant to compare to this one
        Returns:
        true iff the two invariants represent the same mathematical formula. Does not consider

      • isExclusiveFormula

        @Pure
public boolean isExclusiveFormula​(Invariant other)
        Description copied from class: Invariant
        Returns true iff the two invariants represent mutually exclusive mathematical formulas -- that is, if one of them is true, then the other must be false. This method does not consider the context such as variable names, confidences, sample counts, value counts, or related quantities.
        Overrides:
        isExclusiveFormula in class Invariant
        Parameters:
        other - the other invariant to compare to this one
        Returns:
        true iff the two invariants represent mutually exclusive mathematical formulas
