Support contains 72 out of 1992 places. Attempting structural reductions.
Starting structural reductions in SI_LTL mode, iteration 0 : 1992/1992 places, 3096/3096 transitions.
Drop transitions (Trivial Post-Agglo cleanup.) removed 882 transitions
Trivial Post-agglo rules discarded 882 transitions
Performed 882 trivial Post agglomeration. Transition count delta: 882
Iterating post reduction 0 with 882 rules applied. Total rules applied 882 place count 1992 transition count 2214
Reduce places removed 882 places and 0 transitions.
Iterating post reduction 1 with 882 rules applied. Total rules applied 1764 place count 1110 transition count 2214
Performed 455 Pre agglomeration using Quasi-Persistent + Divergent Free condition..
Pre-agglomeration after 2 with 455 Pre rules applied. Total rules applied 1764 place count 1110 transition count 1759
