Starting structural reductions, iteration 1 : 750/854 places, 1521/2230 transitions.
Applied a total of 0 rules in 40 ms. Remains 750 /750 variables (removed 0) and now considering 1521/1521 (removed 0) transitions.
Finished structural reductions, in 2 iterations. Remains : 750/854 places, 1521/2230 transitions.
Finished random walk after 12 steps, including 0 resets, run found a deadlock after 3 ms. (steps per millisecond=4 )
