Minimal Covers of Formal Languages
Let L1; L2 be languages. If L1 L2, then we say that L2 covers L1. Let C;D be classes of languages over . We call a cover L2 2 C of L1 a C-minimal cover with respect to D if, for all L0 2 C, L1 L0 L2 implies L2 L0 2 D. We examine in detail the particular cases of minimal regular covers and minimal context-free covers, both with respect to nite languages. The closure properties of the class of la...
متن کاملCycle Double Covers of Graphs with Disconnected Frames
Continuing work initiated by Häggkvist and Markström, we show in this paper that certain disconnected frames guarantee the existence of a cycle double cover. Specifically, we show that the disjoint union of a Kotzig and a sturdy graph forms a good frame.
متن کاملMCMC With Disconnected State Spaces
Bayes Nets simplify probabilistic models, making it easy to work with these models. Unfortunately, sometimes people devise models that are too complicated to allow calculation of exact probabilities, so they instead use approximate inference, such as Markov Chain Monte Carlo (MCMC). However, MCMC can fail if the Bayes Net has zero-probability states that “disconnect” the state space. In this pa...
متن کاملOn I-extremally Disconnected Spaces
We have introduced and investigated the notion of I-extremal disconnectedness on ideal topological spaces. First, we found that the notions of extremal disconnectedness and I-extremal disconnectedness are independent of each other. About the letter one, we observed that every open subset of an I-extremally disconnected space is also an I-extremally disconnected space. And also, in extremally di...
متن کاملCompact and extremally disconnected spaces
Viglino defined a Hausdorff topological space to be C-compact if each closed subset of the space is anH-set in the sense of Velǐcko. In this paper, we study the class of Hausdorff spaces characterized by the property that each closed subset is an S-set in the sense of Dickman and Krystock. Such spaces are calledC-s-compact. Recently, the notion of strongly subclosed relation, introduced by Jose...
