Many checking sequence generation methods use an adaptive distinguishing sequence (ADS), which is an experiment that distinguishes the states of the specification machine. Furthermore, it has been shown that the use of shorter ADSs yields shorter checking sequences. It is also known, on the other hand, that constructing a minimum cost ADS is an NP-hard problem and it is NP-hard to approximate. This motivates studying and investigating effective ADS construction methods. Objective: The main objective of this paper is to suggest new methods that can compute compact ADSs to be used in the construction of checking sequences. Method: We briefly present the existing ADS construction algorithms. We then propose generalizations of these approaches with a set of heuristics. We also conduct experiments to compare the size of the resultant ADSs and the length of the checking sequences constructed using these ADSs. Results: The results indicate that when the ADSs are constructed with the proposed methods, the length of the checking sequences may reduce up to 54% (40% on the average). Conclusions: In this paper, we present the state of the art ADS construction methods for FSMs and we propose generalizations of these methods. We show that our methods are effective in terms of computation time and ADS quality.
