The sweep-line state space exploration method
The sweep-line method exploits intrinsic progress in concurrent systems to alleviate the state explosion problem in explicit state model checking. The concept of progress makes it possible to delete states from the memory during state space exploration and thereby reduce peak memory usage. The contribution of this paper is twofold. First, we provide a coherent presentation of the sweep-line the...
متن کاملCombining the Sweep-Line Method with the Use of an External-Memory Priority Queue
The sweep-line method is an explicit-state model checking technique that uses a notion of progress to delete states from internal memory during state space exploration and thereby reduce peak memory usage. The sweep-line algorithm relies on the use of a priority queue where the progress value assigned to a state determines the priority of the state. In earlier implementations of the sweep-line ...
متن کاملChecking Language Inclusion On-The-Fly with the Sweep-line Method
The sweep-line state space method allows states to be deleted from memory during state exploration, thus alleviating state explosion. Properties of the system (such as the absence of deadlocks) can then be verified on-the-fly. This paper presents an extension to the sweepline method that allows on-the-fly checking of language inclusion, which is useful for protocol verification. This has been i...
متن کاملSweep-Line Analysis of TCP Connection Management
State space explosion is a key problem in the analysis of finite state systems. The sweep-line method is a state exploration method which uses a notion of progress to allow states to be deleted from memory when they are no longer required. This reduces the peak number of states that need to be stored, while still exploring the full state space. The technique shows promise but has never achieved...
متن کاملA Sweep-Line Method for State Space Exploration
We present a state space exploration method for on-the-fly verification. The method is aimed at systems for which it is possible to define a measure of progress based on the states of the system. The measure of progress makes it possible to delete certain states on-the-fly during state space generation, since these states can never be reached again. This in turn reduces the memory used for stat...
