| 7 | Synopsis [Functions for vacuity detection.] |
---|

---|
| 9 | Description [This file contains the functions implementing vacuity |
---|
| 10 | detection for CTL. A CTL formula passes vacuously if it can be strengthened |
---|
| 11 | by replacing subformulae by "bottom" (either TRUE or FALSE, depending on the |
---|
| 12 | negation parity) without changing the outcome of model checking. Likewise, |
---|
| 13 | a formula fails vacuously if it can be weakened by replacing subformulae by |
---|
| 14 | top (the negation of bottom) and still fail. Under the assumption that a |
---|
| 15 | formula is represented by a parse tree (as opposed to a more general parse |
---|
| 16 | DAG) each subformula has a given negation parity. Bottom stands for FALSE |
---|
| 17 | if the replaced subformula appears under an even number of negation; it |
---|
| 18 | stands for TRUE otherwise. Since all CTL operators besides neagtion are |
---|
| 19 | monotonically increasing in their operands, replacing a subformula with |
---|
| 20 | bottom result in a stronger property, that is, one that implies the original |
---|
| 21 | one. A dual argument applies to replacements with top.<p> |
---|
| 22 | This file contains two algorithms for CTL vacuity detection: The original |
---|
| 23 | one of Beer et al. (CAV97), and an extension of the thorough vacuity |
---|
| 24 | detection algorithm of Purandare and Somenzi (CAV2002), also known as "CTL |
---|
| 25 | vacuum cleaning."<p> |
---|
| 26 | The algorithm of Beer et al. applies to passing weak ACTL (w-ACTL) |
---|
| 27 | properties. Roughly speaking, in a w-ACTL property each binary opeartor has |
---|
| 28 | at least one child that is a propositional formula. A w-ACTL formula |
---|
| 29 | contains a unique smallest important subformula. This is replaced by bottom |
---|
| 30 | to produce a witness formula. If the witness formula passes, then the |
---|
| 31 | original formula passed vacuously; otherwise, the counterexample to the |
---|
| 32 | witness formula is an interesting witness to the original one.<p> |
---|
| 33 | The implementation of the CTL vacuum cleaning algorithm in this file applies |
---|
| 34 | to both passing and failing CTL properties. For each formula, replacement |
---|
| 35 | is attempted for all leaves, therefore identifying many more cases of |
---|
| 36 | vacuity. All the replacements are dealt with in one traversal of the parse |
---|
| 37 | tree of the formula, paying attention to combining the cases that produce |
---|
| 38 | identical sets of states. For this reason, thorough vacuity detection is |
---|
| 39 | usually much cheaper than running as many model checking experiments as |
---|
| 40 | there are leaves.] |
