FORMULA PolyORBNT-COL-S10J40-ReachabilityCardinality-10 TRUE TECHNIQUES STRUCTURAL_REDUCTION TOPOLOGICAL SAT_SMT
Incomplete Parikh walk after 2900 steps, including 235 resets, run finished after 26 ms. (steps per millisecond=111 ) properties seen :[0] could not realise parikh vector
Support contains 67 out of 802 places. Attempting structural reductions.
Starting structural reductions, iteration 0 : 802/802 places, 1573/1573 transitions.
Performed 2 Post agglomeration using F-continuation condition.Transition count delta: 2
Iterating post reduction 0 with 2 rules applied. Total rules applied 2 place count 802 transition count 1571
Reduce places removed 2 places and 0 transitions.
Iterating post reduction 1 with 2 rules applied. Total rules applied 4 place count 800 transition count 1571
Performed 44 Pre agglomeration using Quasi-Persistent + Divergent Free condition..
