  • 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 0100 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".
