1. Technically, this is often achieved by refuting the negation of the theorem.
2. A related classification scheme for parallel reasoning systems along three axes is briefly described in [20]. The axes refer to the homogeneity, the separation of the intermediate results, and the synchroneity of a parallel system. Besides the synchronization aspects, these issues can be mapped onto the concepts of partitioning/competition and cooperativeness in our classification, respectively.
3. The different possibilities for performing a reduction step are not explored in parallel.
4. As in PARTHEO (cf. Section 3.1.2), the Model Elimination reduction steps are not tried in parallel.
5. SASS stands for “Simultaneous Access of Selectively Shared objects”.
