Consider a directed graph G = (V, E) with n vertices and a root vertex r ∈ V . The DMDST problem for G is one of constructing a spanning tree rooted at r, whose maximal degree is...
Abstract. We propose a novel approach to clustering, based on deterministic analysis of random walks on the weighted graph associated with the clustering problem. The method is cen...
Abstract. Regular Model-Checking (RMC) is a technique for the formal verification of infinite state systems based on the theory of regular languages. In the paper “Beyond Regul...
Abstract. This paper studies a recently developed an approach to reasoning about mutable data structures, which uses an assertion language with spatial conjunction and implication ...

This paper has the following goals: – To survey some of the recent developments in the field of derandomization. – To introduce a new notion of time-bounded Kolmogorov complex...
For any class C und closed under NC1 reductions, it is shown that all sets complete for C under first-order (equivalently, Dlogtimeuniform AC0 ) reductions are isomorphic under ...
Abstract. This paper addresses the state explosion problem in automata based LTL model checking. To deal with large space requirements we turn to use a distributed approach. All th...
Hierarchical Message Sequence Charts are a well-established formalism to specify telecommunication protocols. In this model, numerous undecidability results were obtained recently ...
Abstract. Among the branching-time temporal logics used for the specification and verification of systems, CTL+ , FCTL and ECTL+ are the most notable logics for which the precise...
