Abstract
Model checking techniques have not been effective in important
classes of software systems---systems characterized by large (or infinite)
input domains with interrelated linear and non-linear constraints
over the system variables. Various model abstraction techniques
have been proposed to address this problem, but their
effectiveness in practice is limited by two factors; first, the
abstraction process is manual and requires a great deal of
ingenuity, and, second, the abstraction may be coarse and
introduce too many spurious behaviors to provide meaningful
analysis results.
In this paper, we wish to propose domain reduction
abstraction based on data equivalence and trajectory
reduction as an alternative and complement to other abstraction
techniques. Our technique applies the abstraction to the input
domain (environment) instead of the model and is applicable to
constraint-free and deterministic constrained data
transition systems. Our technique is automatable with some minor
restrictions. We provide formal proofs for the theoretical
soundness of the technique, algorithms for automation, and
an illustration of the approach with examples.
