Free SCC test removed 2483 places
Drop transitions removed 19160 transitions
Ensure Unique test removed 212 transitions
Reduce isomorphic transitions removed 19372 transitions.
Applied a total of 1 rules in 117 ms. Remains 17 /2500 variables (removed 2483) and now considering 32/19404 (removed 19372) transitions.
Finished structural reductions in REACHABILITY mode , in 1 iterations and 118 ms. Remains : 17/2500 places, 32/19404 transitions.
