* full.ltl
|
||||
|
||||
A list of 1000 large randomly generated LTL formulae with ./randtgba.
|
||||
|
||||
=======
|
||||
USAGE
|
||||
=======
|
||||
|
||||
Use the stats program.
|
||||
Usage : ./stats ltl_file
|
||||
Where ltl_file is a file with a single LTL formula per line.
|
||||
|
||||
==========================
|
||||
INTERPRETING THE RESULTS
|
||||
==========================
|
||||
|
||||
Results can be found in file 'results'.
|
||||
Here is the list of the measured values:
|
||||
- Accepting Strongly Connected Components.
|
||||
Total number of accepting SCC.
|
||||
- Dead Strongly Connected Components.
|
||||
Total number of dead SCC.
|
||||
An SCC is dead if no accepting SCC is reachable from it.
|
||||
- Accepting Paths.
|
||||
Number of maximal accepting paths.
|
||||
An path is maximal and accepting if it ends in an accepting
|
||||
SCC that is only dead (i.e. non accepting) successors, or no
|
||||
successors at all.
|
||||
- Dead Paths.
|
||||
Number of paths to a terminal dead SCC.
|
||||
A terminal dead SCC is a dead SCC without successors.
|
||||
- Max Effective Splitting.
|
||||
A clue to measure the potential effectiveness of splitting the formula.
|
||||
This is the maximum number of possible sub automata with unique states.
|
||||
Beyond this threshold, more sub automata can be generated, but all their
|
||||
states will be included in some of the previous automata.
|
||||
- Self Loops per State.
|
||||
Number of self loops.
|
||||
A self loop is a transition from a state to itself.
|
||||
|
||||
For each of these measured value, we provide the following statistics
|
||||
computed on all the formulae in ltl_file:\
|
||||
- Min
|
||||
- Max
|
||||
- Mean
|
||||
- Median
|
||||
- Standard Deviation

This directory contains the input files and test program used to produce

the measures for our new method consisting in splitting the automaton

corresponding to the formula in order to obtain smaller synchronised product.
|

This new method could lead to parallel computation of emptiness checks for

possibly faster results.

Variations of the leader election protocol with extinction from

Tel, Introduction to Distributed Algorithms, 1994, Chapter 7. The

network in the model consists of three nodes. In Variant 1, the

same node wins every time, in Variant 2, each node gets a turn at
|

winning the election. These specifications were originally

The corresponding TGBA for the Promela models introduced above.
|
||||
They were translated by pml2tgba.pl (located in bench/emptchk/)
|
||||
into an input format readable by SPOT.
|
||||
Promela inputs can be translated in 4 different graphs.
|
||||
For instance eeaean1.pml is translated as
|
||||
- eeaean1.tgba full translation
|
||||
- eeaean1R.tgba reduced translation
|
||||
The "reduced" translation uses Spin's partial order reductions.
|
||||
|
||||
* results/<model_name>
|
||||
|
||||
For each <model_name>.tgba model in models you can find a simple text file
|
||||
named <model_name>.
|
||||
Each file present the results of our own benchmarks.
|
||||
See the INTERPRETING RESULTS section for further details.
|
||||
|
||||
=======
|
||||
USAGE
|
||||
=======
|
||||
|
||||
Use the cutscc program.
|
||||
Usage: ./cutscc ltl_formulae split_number [model]
|
||||
Where
|
||||
- ltl_formulae is a ltl file with one formula per line.
|
||||
- split_number is the maximum number of sub automata after splitting.
|
||||
Remember this is a maximum value, the effective splitting can be between
|
||||
1 and split_number automata.
|
||||
- model is the .tgba input file translated from Promela for Spot.
|
||||
If no model is speficied, a random graph with 10 000 nodes will be
|
||||
generated.
|
||||
|
||||
Sample examples :
|
||||
./cutscc models/eeaean.ltl 2 models/eeaean1.tgba
|
||||
./cutscc models/formulae.ltl 2
|
||||
|
||||
==========================
|
||||
INTERPRETING THE RESULTS
|
||||
==========================
|
||||
|
||||
By default, all results are printed on standard output. Redirect them
|
||||
with ">" to erase files in cut-results/ or to create new benchs files.
|
||||
|
||||
The output looks as follow, first, the global header:
|
||||
| Reference automaton has 49332 states.
|
||||
| Trying to split each automaton in 9 sub automata.
|
||||
| Each operation is repeated 100 times to improve precision.
|
||||
First, if we specified a single model, we have the size of our model.
|
||||
The second line is a recall of split_number value.
|
||||
The third line is the number of iteration repeated to increase the precision
|
||||
of benchmarks for each key operation. It greatly slows down the whole process.
|
||||
To measure the elapsed time we simply compute the difference between
|
||||
gettimeofday() before and after our operation.
|
||||
|
||||
For each formula, the result looks as follow :
|
||||
| Formula 9
|
||||
| !((<>[](noLeader || zeroLeads || oneLeads || twoLeads)) && (<>[]((zeroLeads -> (zeroLeads U (noLeader U twoLeads))))) && (<>[]((oneLeads -> (oneLeads U (noLeader U zeroLeads))))) && (<>[]((twoLeads -> (twoLeads U (noLeader U oneLeads))))))
|
||||
|
|
||||
First, the number of the formula, i.e the corresponding line in the ltl file.
|
||||
On the following line the formula is recalled
|
||||
|
||||
| Full Product : 247864 states in 0.002611s
|
||||
| 361 unique states visited
|
||||
| 27 strongly connected components in search stack
|
||||
| 412 transitions explored
|
||||
| 361 items max in DFS search stack
|
||||
|
|
||||
Stats of the synchronised product and emptiness check computed on the main
|
||||
unsplitted automaton.
|
||||
|
||||
| Splitting in 0.000212s
|
||||
| Base automaton splitted in 4 automata.
|
||||
|
|
||||
Details about splitting time and number of sub automata created.
|
||||
Here, we wished every formula would have been splitted in 9, but here
|
||||
it could only be splitted in 4.
|
||||
|
||||
| Product 1 : 99871 states in 0.002614s
|
||||
| 361 unique states visited
|
||||
| 27 strongly connected components in search stack
|
||||
| 412 transitions explored
|
||||
| 361 items max in DFS search stack
|
||||
|
|
||||
| Product 2 : 49332 states in 0.297583s
|
||||
| No accepting path.
|
||||
|
|
||||
| Product 3 : 49332 states in 0.297967s
|
||||
| No accepting path.
|
||||
|
|
||||
| Product 4 : 49332 states in 0.296978s
|
||||
| No accepting path.
|
||||
|
|
||||
Details concerning synchronised product size and emptiness check on each
|
||||
sub automaton, in the same format as above for the full formula.
|
||||
|
||||
| Total split products size : 247867
|
||||
| Additionnal states created : 3
|
||||
| Additionnal states ratio : 0.000012
|
||||
| Cutting and computing time : 0.002826s
|
||||
| Time gain -0.000214s
|
||||
Overall data for this formula, we compute the size of our splitted
|
||||
synchronised products by simply adding them. This is an important
|
||||
factor because sometimes an excessively large number of states are generated
|
||||
with this method compared to the original product.
|
||||
The two last lines give the speed results of splitting and computing emptiness
|
||||
check on the sub automata.
|
||||
If there is an accepting path, we take the shortest time because it means an
|
||||
early stop in our algorithm, we can stop computation for other sub automata.
|
||||
If there are no accepting path, we take the longest time because it means a
|
||||
mandatory full traversal of all automaton.
|
||||
|
||||
At the end we sum the computation times for the full formula and the splitted
|
||||
formula:
|
||||
| Full 3.145159s
|
||||
| Cutting 0.000212s
|
||||
| Split 2.522595s
|
||||
This is more or less significant, sometime splitting will greatly improve
|
||||
speed for a single formula and will have small or no impact on others.
