SETHEO goes software engineering: Application of ATP to software reuse
The results of our experiments with SETHEO are very encouraging. Nevertheless, many improvements on this approach have to be made before this tool can really be used in industry. Due to the hard time-constraints (“results while-u-wait”), the reduction of proof-tasks, both in complexity and number is of central importance. A powerful chain of filters (ranging from signature matching to dis-proving techniques) must ensure that only a few proof tasks remain to be processed by the automated theorem prover. For these, a set of axioms as small as possible and valuable lemmas must be selected. Furthermore, work will be done to improve the approximation of induction.
This application of automated theorem proving technique carries the unique feature that soundness and completeness are not absolutely vital — unsound and incomplete methods only reduce the precision and recall of the retrieval tool. This allows interesting and promising techniques of approximating proofs (e.g., by filter chains or iteration) to be explored which will help to lead to an industrial application of SETHEO.
