Using State Symmetries to Speed up Symmetry Reduction in Model Checking
نویسنده
چکیده
Concurrent systems with many replicated components often exhibit a lot of symmetries. When using model checking to verify such systems, this leads to a redundant search over equivalent parts of the state-space. Verification can even be intractable for concurrent systems due to the state-space explosion problem which model checking suffers from. Considerable memory savings can be achieved by using symmetry reduction when verifying systems which contain symmetries. However, sometimes verification time can significantly increase with symmetry reduction because of the time required to compute representatives of equivalent states. Therefore we investigate the efficient use of state symmetries. The use of state symmetries aims to avoid redundant computations of representatives.

Efficient Symmetry Reduction and the Use of State Symmetries for Symbolic Model Checking
One technique to reduce the state-space explosion problem in temporal logic model checking is symmetry reduction. The combination of symmetry reduction and symbolic model checking by using BDDs suffered a long time from the prohibitively large BDD for the orbit relation. Dynamic symmetry reduction calculates representatives of equivalence classes of states dynamically and thus avoids the constr...
متن کاملDiscovering Symmetries
When model checking concurrent software applications, symmetry reduction techniques narrow dramatically the size of the state space search by identifying computations that, because of symmetries in the system, are redundant. While state-exploration algorithms exploiting symmetry reduction are well developed, little has been done in discovering the nature of the symmetries of a system. What is e...

Symmetry reduction is a model checking technique that can help alleviate the problem of state space explosion, by preventing redundant state space exploration. In previous work, we have developed three effective approaches to symmetry reduction for B that have been implemented into the ProB model checker, and we have proved the soundness of our state symmetries. However, it is also important to...
متن کاملAutomatic Symmetry Detection for Model Checking Using Computational Group Theory
We present an automatic technique for the detection of structural symmetry in a model directly from its Promela specification. Our approach involves finding the static channel diagram of the model, a graphical representation of channel-based system communication; computing the group of symmetries of this diagram; and computing the largest possible subgroup of these symmetries which induce autom...
