Zusammenfassung:Abstract: "In these notes we study run-time properties of general programs w.r.t. constructive negation, i.e. termination and properties of the form of the arguments of the literals selected during the execution. We consider here SLD-CNF resolution, i.e. resolution with constructive negation and arbitrary selection rule, and LD-CNF resolution, i.e. resolution with constructive negation and Prolog selection rule. We show that the class of programs which terminate for all ground goals for arbitrary (resp. Prolog) selection rule coincides with the so-called acyclic (resp. acceptable) programs, and that SLD-CNF (resp. LD-CNF) resolution is sound and complete w.r.t. Clark's semantics for bounded goals and acyclic (resp. acceptable) programs
These results are applied to the study of run-time properties of general programs: two proof methods are introduced and their soundness is proven respectively w.r.t. SLD-CNF and LD-CNF resolution.
