neutrosophic set
     
         A generalisation of the {intuitionistic set},
        classical set, {fuzzy set}, {paraconsistent set}, {dialetheist
        set}, {paradoxist set}, {tautological set} based on
        {Neutrosophy}.  An element x(T, I, F) belongs to the set in
        the following way: it is t true in the set, i indeterminate in
        the set, and f false, where t, i, and f are real numbers taken
        from the sets T, I, and F with no restriction on T, I, F, nor
        on their sum n=t+i+f.
     
        The neutrosophic set generalises:
     
        - the {intuitionistic set}, which supports incomplete set
        theories (for 0100 and i=0, with both
        t,f<100);
     
        - the {dialetheist set}, which says that the intersection of
        some disjoint sets is not empty (for t=f=100 and i=0; some
        paradoxist sets can be denoted this way).
