Requirement-Based Cooperative Theorem Proving

We examine an approach for demand-driven cooperative theorem proving. We brieey point out the problems arising from the use of common success-driven cooperation methods, and we propose the application of our approach of requirement-based cooperative theorem proving. This approach allows for a better orientation on current needs of provers in comparison with conventional cooperation concepts. We introduce an abstract framework for requirement-based cooperation and describe two instantiations of it: Requirement-based exchange of facts and sub-problem division and transfer via requests. Finally, we report on experimental studies conducted in the areas superposition and unfailing completion .
