“…Context-enhanced directed model-checking techniques introduced in [23] to tackle state explosion problem. The goal is to find error states in concurrent systems with the objectives of developing a heuristic search to explore those parts of the state space belonging to the same part of the system using the notion of interference context.…”

Debugging software code has been a challenge for software developers since the early days of computer programming. A simple need, because the world is run by software. So perhaps the biggest engineering challenge is finding ways to make software more reliable. This review provides an overview of techniques developed over time in the field of software model checking to solve the problem of detecting errors in program code. In addition, the challenges posed by this technology are discussed and ways to mitigate them in future research and applications are proposed. A comprehensive examination of the various model verification methods used to detect program code errors is intended to lay the foundation for future research in this area.

“…Directed model checking has recently found much attention in different versions to efficiently detect error states in concurrent systems [4,6,7,10,14,15,[19][20][21][22][23]. In the following, we give a very brief comparison of downward pattern refinement with other PDB heuristics.…”

“…To be able to debug a system effectively, it is important to have short or preferably shortest possible error traces in such cases. Directed model checking (DMC) is a well established technique to find reachable error states in concurrent systems and has recently found much attention [4,6,7,10,14,15,[19][20][21][22][23]. The main idea of DMC is to focus on those parts of the state space that show promise to contain reachable error states.…”

Abstract. Directed model checking is a well-established technique for detecting error states in concurrent systems efficiently. As error traces are important for debugging purposes, it is preferable to find as short error traces as possible. A wide spread method to find provably shortest error traces is to apply the A * search algorithm with distance heuristics that never overestimate the real error distance. An important class of such distance estimators is the class of pattern database heuristics, which are built on abstractions of the system under consideration. In this paper, we propose a systematic approach for the construction of pattern database heuristics. We formally define a concept to measure the accuracy of abstractions. Based on this technique, we address the challenge of finding abstractions that are succinct on the one hand, and accurate to produce informed pattern databases on the other hand. We evaluate our approach on large and complex industrial problems. The experiments show that the resulting distance heuristic impressively advances the state of the art.

“…A useful heuristic for detection of concurrency errors is to prefer thread context switches (thread interleavings) [7] -when the state s being processed was reached by execution of thread t, the function order puts transitions associated with threads other than t at the beginning of the list. Another useful heuristic gives preference to transitions that may interfere with some of the previous transitions on the current state space path [22]. Two transitions can interfere, for example, if they are associated with different threads and contain instructions that access the same shared variables.…”

Abstract. While exhaustive state space traversal is not feasible in reasonable time for complex concurrent programs, many techniques for efficient detection of concurrency errors and testing of concurrent programs have been introduced in recent years, such as directed search and context-bounded model checking. We propose to use depth-first traversal with randomized backtracking, where it is possible to backtrack from a state before all outgoing transitions have been explored, and the whole process is driven by random number choices. Experiments with a prototype implementation in JPF on several Java programs show that, in most cases, fewer states must be explored to find an error with our approach than using the existing techniques.
