| 7 | Synopsis [Routines for image and preimage computations using transition |
---|
| 8 | function method.] |
---|
| 9 | |
---|
| 10 | Description [Transition function method is implemented as a part of the |
---|
| 11 | hybrid image computation (refer to "To Split or to Conjoin: The Question |
---|
| 12 | in Image Computation", In-Ho Moon et. al. in the proceedings of DAC00.) |
---|
| 13 | The hybrid method starts with transition function method based on splitting, |
---|
| 14 | then switches to transition relation method based on conjunctions. The |
---|
| 15 | decision is based on computing variable lifetimes from dependence matrix |
---|
| 16 | dynamically at every recursion. |
---|
| 17 | |
---|
| 18 | The transition function method itself also can be used as an image_method, |
---|
| 19 | however we do not recommend to use this method for general purpose. This |
---|
| 20 | method can be used for experimental purpose. However, this method performs |
---|
| 21 | quite well for most approximate reachability and some examples on exact |
---|
| 22 | reachability. |
---|
| 23 | |
---|
| 24 | There are two image computation methods in transition function method; |
---|
| 25 | input splitting (default) and output splitting. Also three preimage |
---|
| 26 | computation methods in transition function method are implemented; domain |
---|
| 27 | cofactoring (default), sequential substitution, and simultaneous substitution. |
---|
| 28 | |
---|
| 29 | The performance of transition function method is significantly depending on |
---|
| 30 | both the choice of splitting variable and the use of image cache. However, |
---|
| 31 | the hybrid method does not use image cache by default. Since the recursion |
---|
| 32 | depths are bounded (not so deep) in the hybrid method, the cache hit ratio |
---|
| 33 | is usually very low. |
---|
| 34 | |
---|
| 35 | The implementation of the transition function method and the hybrid method |
---|
| 36 | is very complicate since there are so many options. For details, try |
---|
| 37 | print_tfm_options and print_hybrid_options commands in vis, also more |
---|
| 38 | detailed descriptions for all options can be read by using help in vis |
---|
| 39 | for the two commands. |
---|
| 40 | |
---|
| 41 | The hybrid method can start with either only function vector or only |
---|
| 42 | transition relation, as well as with both function vector and transition |
---|
| 43 | relation. In case of starting with only the function vector, when we switch |
---|
| 44 | to conjoin, transition relation is built on demand. This method may consume |
---|
| 45 | less memory than the others, but it may take more time since it is a big |
---|
| 46 | overhead to build transition relation at every conjunction. To reduce this |
---|
| 47 | overhead, the hybrid method can start with both function vector and transition |
---|
| 48 | relation (default). In the presense of non-determinism, the hybrid mehtod |
---|
| 49 | also can start with only transition relation without the function vector.] |
