We give an overview of GRIP, a symmetry reduction tool for the probabilistic model checker PRISM, together with experimental results for a selection of example specifications. 1 ...
This paper describes a compositional proof strategy for verifying properties of requirements specifications. The proof strategy, which may be applied using either a model checker ...
The evolution of software systems over many years often leads to unnecessarily complex and in exible designs which in turn lead to a huge amount of e ort for enhancements and main...
During testing, the execution of valid cases is only one part of the task. Checking the behavior in boundary situations and in the presence of errors is an equally important subje...
Statistical models fit to data often require extensive and challenging re-estimation before achieving final form. For example, outliers can adversely affect fits. In other cas...
