Starting structural reductions, iteration 1 : 580/664 places, 1251/1940 transitions.
Applied a total of 0 rules in 50 ms. Remains 580 /580 variables (removed 0) and now considering 1251/1251 (removed 0) transitions.
Finished structural reductions, in 2 iterations. Remains : 580/664 places, 1251/1940 transitions.
Finished Parikh directed walk after 10 steps, including 0 resets, run found a deadlock after 2 ms. (steps per millisecond=5 )
