This contains most of the a benchmark used for the paper
|
|
|
|
"Compositional Approach to Suspension and Other Improvements to LTL
|
|
Translation", Tomáš Babiak, Thomas Badie, Alexandre Duret-Lutz,
|
|
Mojmír Křetínský, and Jan Strejček.
|
|
|
|
To appear in the proceedings of Spin'13.
|
|
|
|
By "most" we means that some lines of the table will actually be missing
|
|
because we cannot compute them with the current version of Spot. The
|
|
missing lines are those with a small "a", that use the old SCC-based
|
|
simplification, and not the new one which is presented in section 4.1
|
|
of the paper.
|
|
|
|
If you have any interest in reproducing the data from the paper, using
|
|
exactly the same versions (yes, that's a plural), please head over to
|
|
http://www.lrde.epita.fr/~adl/spin13/
|
|
|
|
Keep in mind that as Spot is evolving, the results from this benchmark
|
|
may evolve (hopefully for the best!) with time.
|
|
|
|
The benchmark has been updated to use ltl3ba 1.1.0 released on
|
|
2014-01-23 (because the set of optimizations that are now activated
|
|
by default is different).
|
|
|
|
Running instructions
|
|
====================
|
|
|
|
To run the benchmark:
|
|
|
|
1) Now configure and compile the current tarball with
|
|
./configure --disable-shared --disable-devel
|
|
make
|
|
but to not install it.
|
|
2) Go to directory bench/spin13/ and run the script "run.sh",
|
|
this will just build "run.mk"
|
|
3) Run "make -f run.mk -j4", adjusting "-j8" to the number of
|
|
cores that your computer have.
|
|
|
|
The run.mk makefile will launch several instances of ltlcross in
|
|
parallel (depending on the -j argument). There are 22 of them
|
|
to run in total. Once that is done, the different data are
|
|
collated into a LaTeX file (using the ../ltl2tgba/sum.py script)
|
|
which is then compiled to PDF (using latexmk). Finally, all
|
|
data are compacted into a tarball named with the date.
|
|
|

Results
|
|
=======
|
|
|
|
The results are more detailed that Table 1 in the Spin'13 paper.
|
|
|
|
ba-sum.pdf and tgba-sum.pdf show the main results over several sets
|
|
of formulae:
|
|
- known.ltl is the set described in the paper;
|
|
- new-fair3.ltl.pos is what we call fair3.ltl in the paper;
|
|
- new-strong2.ltl.pos is what we call strong2.ltl in the paper.
|
|
The extra sets are:
|
|
- new-ltl.pos: the set of random \varphi_i formula used to build
|
|
new-fair3.ltl.pos and new-strong2.ltl.pos;
|
|
- new-fair2.ltl.pos: the above formulae combined with weak
|
|
fairness hypothesis of the form (FG(a)->GF(b));
|
|
- new-strong1.ltl.pos: simimular to strong2 but using only
|
|
one strong fairness hypothesis of the form
|
|
(GF(a)->GF(b)).
|
|
|
|
Additionally, for all *.ltl.pos files, we have an *.ltl.neg file that
|
|
contains the negated formulas.
|
|
|
|
These 11 sets are translated to TGBA or BA using different
|
|
translation configurations. Many of the configurations should be
|
|
recognized from the name in the paper. The "Early" lines describe
|
|
an extra experiement (not discussed in the paper), where
|
|
composition of the suspended subformula starts on the transition
|
|
that enters an accepting SCC (not in the SCC itself).
|
|
|
|
In addition to the summaries in ba-sum.pdf and tgba-sum.pdf, detailled
|
|
results are provided as CSV files, slightly better formated JSON
|
|
files, and in HTML pages that can be used to explore the results
|
|
interactively. (It probably does not work with Internet Explorer. If
|
|
you have problems, install FireFox or Chrome.)
