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.] |
