Abstract: According to the random truth degree, the random truth degree of formula is obtained under the Γ-limited information control in two-valued propositional logic. The Γ- limitation random similarity and Γ- limitation random pseudo metric of the formula are defined respectively. The Γ-random truth degree expression of Γ- limitation random pseudo metric from formula to conclusion set are got under the Γ-limitation of finite information. So these studies become the numerical identification of approximate reasoning’s randomization which is based on the limited information in two-valued propositional logic.

Key words: two-valued propositional logic, information, Γ- limitation random truth degree, Γ- limitation random similarity, Γ- limitation random pseudo metric
