Abstract. This article surveys and gives historical accounts to the algorithmic essentials of directed model checking, a promising bug-hunting technique to mitigate the state explosion problem. In the enumeration process, successor selection is prioritized. We discuss existing guidance and methods to automatically generate them by exploiting system abstractions. We extend the algorithms to feature partial-order reduction and show how liveness problems can be adapted by lifting the search space. For deterministic, finite domains we instantiate the algorithms to directed symbolic, external and distributed search. For real-time domains we discuss the adaption of the algorithms to timed automata and for probabilistic domains we show the application to counterexample generation. Last but not least, we explain how directed model checking helps to accelerate finding solutions to scheduling problems.

“…In the other words, between the amount of I/Os and time efficiency has a relation in the sense that the time efficiency will be improved if the I/O actions reduced. S. Edelkamp et al [70] proposed layered duplicate detection to improve duplicate elimination in external memory model checking. This approach decides which states during searching in the state space should be stored in RAM, and which of them should be stored on disk.…”

Component-based design is a different way of constructing systems which offers numerous benefits, in particular, decreasing the complexity of system design. However, deploying components into a system is a challenging and error-prone task. Model checking is one of the reliable methods that automatically and systematically analyses the correctness of a given system. Its brute-force check of the state space significantly expands the level of confidence in the system. Nevertheless, model checking is limited by a critical problem so-called Sate Space Explosion (SSE). To benefit from model checking, appropriate methods to reduce SSE, is required. In two last decades, a great number of methods to mitigate the state space explosion have been proposed which have many similarities, dissimilarities, and unclear concepts in some cases. This research, firstly, aims at present a review and brief discussion of the methods of handling SSE problem and classify them based on their similarities, principle and characteristics. Second, it investigates the methods for handling SSE problem in verifying Component-based system (CBS) and provides insight into CBS verification limitations that have not been addressed yet. The analysis in this research has revealed the patterns, specific features, and gaps in the state-of-the-art methods. In addition, we identified and discussed suitable methods to soften SSE problem in CBS and underlined the key challenges for future research efforts.

Component-based software development (CBSD) is an alternative approach to constructing software systems that offers numerous benefits, particularly in decreasing the complexity of system design. However, deploying components into a system is a challenging and error-prone task. Model-checking is one of the reliable methods to systematically analyze the correctness of a system. Its brute-force checking of the system's state space assists to significantly expand the level of confidence in the system. Nevertheless, model-checking is limited by a critical problem called state space explosion (SSE). To benefit from modelchecking, an appropriate method is required to reduce SSE. In the past two decades, a great number of SSE reduction methods have been proposed containing many similarities, dissimilarities, and unclear concepts in some cases. This research, firstly, plans to present a review of SSE handling methods and classify them based on their similarities, principle, and characteristics. Second, it investigates the methods for handling SSE problem in the verification process of CBSD and provides insight into the potential limitations, underlining the key challenges for future research efforts.
