Stuttering acceptance computed with spot in 187 ms :[true, (NOT p3), (AND (NOT p3) (NOT p2)), (AND (NOT p3) (NOT p2)), (AND (NOT p3) (NOT p2)), (AND (NOT p3) (NOT p2))]
Stuttering acceptance computed with spot in 180 ms :[true, (NOT p3), (AND (NOT p3) (NOT p2)), (AND (NOT p3) (NOT p2)), (AND (NOT p3) (NOT p2)), (AND (NOT p3) (NOT p2))]
Support contains 2 out of 3131 places. Attempting structural reductions.
Property had overlarge support with respect to TGBA, discarding it for now.
Starting structural reductions in LTL mode, iteration 0 : 3131/3131 places, 3045/3045 transitions.
Applied a total of 0 rules in 430 ms. Remains 3131 /3131 variables (removed 0) and now considering 3045/3045 (removed 0) transitions.
