Wasch- und Badeeinrichtungen; AborteRA). The general model checking problem for CTL. formulae over RA is shown ., the undecidability being observed already on the class of Restricted CTL formulae. The decidability result, however, is obtained for another substantial subset of the logic, called A-CTL.+, which includes all ”linear time” formulae.

Ergebnisse der bisherigen Forschung,erminism and concurrency. We investigate the succinctness of such machines, and the extent to which this succinctness carries over to make the reasoning problem in propositional dynamic logic (PDL) more difficult. The two main results establish that each additional pebble provides inherent exponential power on both fronts.

Maintaining spanning trees of small diameter,Given a graph . with . edges and . nodes, a spanning tree . of ., and an edge . that is being deleted from or inserted into ., we give efficient . algorithms to compute a possible swap for . that minimizes the diameter of the new spanning tree. This problem arises in high-speed networks, particularly in optical networks.

Expressiveness of efficient semi-deterministic choice constructs,are no natural determinate-complete query languages known, more restrictive (the .) and more general (the .) notions of query were considered. Here, we show that the advantage of the second approach over the first is not so much in increased expressiveness, but in the ability of expressing queries more efficiently.
