neutrosophic logic

neutrosophic logic

(logic)
(Or "Smarandache logic") A generalisation of fuzzy logic based on Neutrosophy. A proposition is t true, i indeterminate, and f false, where t, i, and f are real values from the ranges T, I, F, with no restriction on T, I, F, or the sum n=t+i+f. Neutrosophic logic thus generalises:

- intuitionistic logic, which supports incomplete theories (for 0<n<100 and i=0, 0<=t,i,f<=100);

- fuzzy logic (for n=100 and i=0, and 0<=t,i,f<=100);

- Boolean logic (for n=100 and i=0, with t,f either 0 or 100);

- multi-valued logic (for 0<=t,i,f<=100);

- paraconsistent logic (for n>100 and i=0, with both t,f<100);

- dialetheism, which says that some contradictions are true (for t=f=100 and i=0; some paradoxes can be denoted this way).

Compared with all other logics, neutrosophic logic introduces a percentage of "indeterminacy" - due to unexpected parameters hidden in some propositions. It also allows each component t,i,f to "boil over" 100 or "freeze" under 0. For example, in some tautologies t>100, called "overtrue".

Emphasizing advancements and applications to neutrosophics, this text introduces the interval neutrosophic set, which is an instance of the neutrosophic set, describes the interval neutrosophic logic based on neutrosophic sets, a situation which allows for modeling of fuzzy, incomplete, and inconsistent information, and gives a neutrosophic relational data model with a relational data base, and another model in the form of a soft semantic web services agent.
More general is the Neutrosophic Logic [Smarandache, 1995], where the truth (T) and the falsity (F) and the indeterminacy (1) can be any numbers in [0, 1], then 0 [less than or equal to] T + I + F [less than or equal to] 3.
