Counterexample Explanation by Anomaly Detection
Since counterexamples generated by model checking tools are only symptoms of faults in the model, a significant amount of manual work is required in order to locate the fault that...

Directed Explicit State-Space Search in the Generation of Counterexamples for Stochastic Model Checking
Current stochastic model checkers do not make counterexamples for property violations readily available. In this paper we apply directed explicit state space search to discrete- a...

DTMC Model Checking by SCC Reduction
Discrete-Time Markov Chains (DTMCs) are a widely-used formalism to model probabilistic systems. On the one hand, available tools like PRISM or MRMC offer efficient model checking a...

Rebutting formally valid counterexamples to the Humean "is-ought" dictum
Various formally valid counterexamples have been adduced against the Humean dictum that one cannot derive an "ought" from an "is." There are formal rebuttals--s...

Computing Over-Approximations with Bounded Model Checking
Bounded Model Checking (BMC) searches for counterexamples to a property with a bounded length k. If no such counterexample is found, k is increased. This process terminates when ...

Significant Diagnostic Counterexamples in Probabilistic Model Checking
Abstract. This paper presents a novel technique for counterexample generation in probabilistic model checking of Markov chains and Markov Decision Processes. (Finite) paths in coun...

A Framework for Counterexample Generation and Exploration
Model-checking is becoming an accepted technique for debugging hardware and software systems. Debugging is based on the “Check / Analyze / Fix” loop: check the system against a...
