Starting structural reductions, iteration 1 : 410/474 places, 981/1650 transitions.
Applied a total of 0 rules in 56 ms. Remains 410 /410 variables (removed 0) and now considering 981/981 (removed 0) transitions.
Finished structural reductions, in 2 iterations. Remains : 410/474 places, 981/1650 transitions.
Finished Parikh directed walk after 10 steps, including 0 resets, run found a deadlock after 3 ms. (steps per millisecond=3 )
