Penta and Hexa Valued Representation of Neutrosophic Information

no code implementations10 Mar 2016 Vasile Patrascu

Starting from the primary representation of neutrosophic information, namely the degree of truth, degree of indeterminacy and degree of falsity, we define a nuanced representation in a penta valued fuzzy space, described by the index of truth, index of falsity, index of ignorance, index of contradiction and index of hesitation.
