The paper shows a logspace-reduction from the boolean circuit value problem which demonstrates that any relation subsuming bisimilarity and being subsumed by trace preorder (i.e.,...
Abstract. Argumentation is a reasoning model based on the construction and the evaluation of arguments. In his seminal paper, Dung has proe most abstract argumentation framework. I...
Dcpos can be presented by a preorder of generators and inequational relations expressed as covers. Algebraic operations on the generators (possibly with their results being ideals...
We present different techniques for reducing the number of states and transitions in nondeterministic automata. These techniques are based on the two preorders over the set of st...
In this paper we study the problem of mining all frequent queries in a given database table, a problem known to be intractable even for conjunctive queries. We restrict our attent...
