Starting structural reductions in LTL mode, iteration 1 : 51/51 places, 83/84 transitions.
Deduced a syphon composed of 2 places in 0 ms
Applied a total of 0 rules in 1 ms. Remains 51 /51 variables (removed 0) and now considering 83/83 (removed 0) transitions.
Finished structural reductions in LTL mode , in 2 iterations and 10316 ms. Remains : 51/51 places, 83/84 transitions.
Deduced a syphon composed of 2 places in 0 ms
Reduce places removed 2 places and 0 transitions.
Support contains 0 out of 49 places after structural reductions.
