Starting structural reductions, iteration 1 : 360/506 places, 1022/1774 transitions.
Applied a total of 0 rules in 31 ms. Remains 360 /360 variables (removed 0) and now considering 1022/1022 (removed 0) transitions.
Finished structural reductions, in 2 iterations. Remains : 360/506 places, 1022/1774 transitions.
Finished Parikh directed walk after 182 steps, including 0 resets, run found a deadlock after 3 ms. (steps per millisecond=60 )
