Stuttering acceptance computed with spot in 78 ms :[true, (AND (NOT p0) (NOT p1)), (NOT p1)]
Support contains 4 out of 1508 places. Attempting structural reductions.
Starting structural reductions in LTL mode, iteration 0 : 1508/1508 places, 1931/1931 transitions.
Applied a total of 0 rules in 51 ms. Remains 1508 /1508 variables (removed 0) and now considering 1931/1931 (removed 0) transitions.
