| Abstract: | The paper is motivated by the declarative debugging of constraint logic programs. It deals with the theoretical basis of declarative incorrectness diagnosis. It starts with a reformulation of the program semantics in terms of proof tree skeletons, which is suitable for declarative diagnosis study. The program semantics is explained in terms of positive semantics and negative semantics. The problem of wrong answer is treated as an incorrectness of the positive semantics while the problem of missing answer is treated as an incorrectness of the negative semantics. Incorrectness diagnosis is based on a well-founded relation over computation states. |
