An Efficient Method for Computing Exact State Space of Petri Nets With Stopwatches
In this paper, we address the issue of the formal verification of real-time systems in the context of a preemptive scheduling policy. We propose an algorithm which computes the st...

Improvements in BDD-Based Reachability Analysis of Timed Automata
To develop efficient algorithms for the reachability analysis of timed automata, a promising approach is to use binary decision diagrams (BDDs) as data structure for the representa...

Tackling Large State Spaces in Performance Modelling
Stochastic performance models provide a powerful way of capturing and analysing the behaviour of complex concurrent systems. Traditionally, performance measures for these models ar...

Test Plan Generation for Concurrent Real-Time Systems Based on Zone Coverage Analysis
The state space explosion due to concurrency and timing constraints of concurrent real-time systems (CRTS) presents significant challenges to the verification engineers. In this pa...

Fast Algorithms for Large-State-Space HMMs with Applications to Web Usage Analysis
In applying Hidden Markov Models to the analysis of massive data streams, it is often necessary to use an artificially reduced set of states; this is due in large part to the fac...
