Starting structural reductions in REACHABILITY mode, iteration 3 : 418/424 places, 435/437 transitions.
Free-agglomeration rule (complex) applied 1 times.
Iterating global reduction 0 with 1 rules applied. Total rules applied 1 place count 418 transition count 434
Reduce places removed 1 places and 0 transitions.
Iterating post reduction 0 with 1 rules applied. Total rules applied 2 place count 417 transition count 434
Applied a total of 2 rules in 16 ms. Remains 417 /418 variables (removed 1) and now considering 434/435 (removed 1) transitions.
