=======================
The files small.txt, big.txt, and known.txt contain a summary of the
results. Each algorithm is described as two lines formated as
results. Each algorithm is described on two lines formated as
follows.
6: Spot FM (degen)
834 / 2419 / 188 / 2.86 166579 / 8749162 (188)
10: Spot FM (degen)
831 2422 188 | 521 157 | 3.01 | 165971 8723693 (188)
The first line presents the name of the algorithm ("Spot FM (degen)")
and its number for lbtt (6). The number is useless. In this example,
"FM (degen)" means that the Couvreur/FM algorithm is used to translate
LTL formula into a TGBA that is then DEGENeralized. You may want to
look in the file `algorithms' to see which options are used for each
name, if the naming is unclear.
and its number for lbtt (10). The number is useless. In this
example, "FM (degen)" means that the Couvreur/FM algorithm is used to
translate LTL formula into a TGBA that is then DEGENeralized, so you
effectively get a Büchi automaton, which you can compare with that
automata produced by other tools. You may want to look in the file
`algorithms' to see which options are used for each name, if the
naming is unclear.
The second line display 7 values:
1. the total number of states of all generated automata (834)
2. the total number of transitions of all generated automata (2419)
The second line display 9 values:
1. the total number of states of all generated automata (831)
2. the total number of transitions of all generated automata (2422)
3. the total number of acceptance conditions of all generated automata (188)
4. the cumulated translation time in seconds (2.86)
5. the total number of states in the synchronized products (166579)
6. the total number of transitions in the synchronized products (8749162)
7. the number of translated formulae (188)
4. the total number of nondeterministic states in these automata (521)
5. the total number of automata with some nondeterminisitic state (157)
6. the cumulated translation time in seconds (3.01)
7. the total number of states in the synchronized products (165971)
8. the total number of transitions in the synchronized products (8723693)
9. the number of translated formulae (188)
For all these values (but the last!) the smaller number the better.
Notes:
* Small translation times are not accurate because most of the
translators are run through scripts that translate their input
from and their output to the format understood by lbtt. For fast
translators, most of the time is spent through these wrappers.
(For instance Spot's ltl2tgba is run through lbtt-translate, and
depending on how Spot has been configured w.r.t. to dynamic
libraries, ltl2tgba itself is often a shell script that run the
real binary with the locally built libraries.)

b) LBTT use the time() function to measure time, which usually
has only a 0.01s resolution. Multiply this 0.01s by the number
for formulae to get the possible error (e.g. for the above example
188*0.01 = 1.88s, so the 3.01s should be interpreted as "within
3.01-1.88 and 3.01+1.88).
* Some tools will appear to have translated fewer automata than the
others. This normally indicates bugs in the translator (incorrect
