In this paper discovery of default knowledge as proposed by Mollestad [7], [8], [9], [10] is further investigated. Mollestad’s algorithm, as described in [9], is refined and extended in several ways. In particular, new heuristics guiding the search for default decision rules are proposed and evaluated. The results so far have been encouraging when the (modified) framework is compared to other rough set methods.
