摘要:

该文将命题逻辑的定理证明转换为多项式方程的求解问题,从而提出了一种基于非子句的代数化方法.在代数化的过程中,以一种形式化的方式给出了命题公式的文法定义,通过语法, 语义分析实现了命题公式的代数化.此外,又根据特征列的性质,提出了一种逻辑推论自动生成的方法.

Abstract:

A formal definition of proposition formulae was provided by context-free grammar,and the conversion from proposition formulae to polynomials was solved automatically. Using Wu′s Method, the paper presented another solution to the problem of theorem reasoning. In addition, a method for producing logical deduction was introduced.

Key words: propositional calculus, context-free grammar, theorem reasoning, logical deduction, Wu′s Method, propositional calculus, context-free grammar, theorem reasoning, logical deduction
