Truth Degrees Theory and Approximate Reasoning in 3-Valued Propositional Pre-Rough Logic
By means of the function induced by a logical formula A, the concept of truth degree of the logical formula A is introduced in the 3-valued pre-rough logic in this paper. Moreover, similarity degrees among formulas are proposed and a pseudometric is defined on the set of formulas, and hence a possib...
