....[CVWY92, HPY96] algorithm employed to detect accepting (violating) B uchi automaton cycles. This is to be expected because depth first search has been proved to be inherently sequential [Reif85] Their paper reports feasibility (without actual examples) on a nine node 366MHz Pentium cluster. In [BCKP01], B uchi acceptance is reduced to detecting negative cycles (those that have a negative sum of edge weights) in a weighted directed graph. This reduction is achieved by attaching an edge weight of 1 to all outgoing edges out of an accepting state, and a weight of 0 to all other edges. Despite ....

....single computer can be employed to sequentially handle one task at a time. In [5] we presented a parallel algorithm for a fragment of L . 12] introduced a symbolic parallel algorithm for the full calculus. However, both are global so that the transition system has to be constructed totally. [6] presents a model checking algorithm for LTL using a costly parallel cycle detection. Confer [4] for further related work. Our main contribution is the first local parallel model checking algorithm for L that supports interactive debugging and omits a cycle detection, which allows a powerful ....

....parallel computer with a huge amount of memory. Reports by several independent groups ( 33, 28, 17, 4, 3] have confirmed the usefulness of distributed algorithms for the state space generation and reachability analysis. Methods for distributing LTL and CTL model checking have been presented in [1, 2, 8] and [6] respectively. However, until today not much effort has been taken to consider distributed algorithms for fair cycle detection. In our search for an effective distributed algorithm let us first discuss diverse sequential algorithms for fair cycle detection. In explicit algorithms the ....

....The algorithm was chosen not only because of its eciency, but also because a distribution of this algorithm seems to be a natural extension of commonly used veri cation tools such as SPIN. The other reason was that we would like to improve our two distributed algorithms for LTL model checking ([2, 5]) Both of them have used partition functions that randomly distribute the state space among the network nodes. The new technique presented in this paper is independent of them, hence, it provides their natural supplementary improvement. A naive approach to the distribution is obvious. The ....

We intend to implement and experiment other strategies for distribution of the veri cation problem that use additional information gained from the veri ed property. Also, we would like to continue our search for similar improvements achieved through exploring the structure of the modeled ....
