This paper deals with the problem of inference under uncertain information. This is a generalization of a paper of Cardona et al. (1991a) where rules were not allowed to contain n...
In this paper, we focus on the problem of existence of and computing small and large stable models. We show that for every xed integer k, there is a linear-time algorithm to decid...
