摘要
A method of automated proving for unrestricted first-logic to test the satisfiability of clause sets describing an industrial system which applies the instance generation rule ]]>;where &PSgr; is a term, &sgr; a substitution and &PSgr;&sgr; an instance of &PSgr; yielded by the substitution &sgr;, and is characterized in that, instance subtraction is defined as the substraction of the instance &PSgr;&sgr; from &PSgr; resulting in a generalized term which is a triplet &PSgr;, &sgr;, &Lgr; where &Lgr; is a finite set of standard substitutions {&lgr;1, . . . , &lgr;n} and defined by; ;the method further applies an instance subtraction combined with said instance generation rule to get an instance extraction rule defined by; ;where &Sgr; is a set of clauses and &mgr; is a substitution valid for the generalized term &PSgr;&sgr;, &Lgr;, whereby the set &Sgr; can be proven unsatisfiable.
