Graph (complete) has 70 edges and 25 vertex of which 15 are kept as prefixes of interest. Removing 10 places using SCC suffix rule.0 ms
Discarding 10 places :
Also discarding 10 output transitions
Drop transitions (Output transitions of discarded places.) removed 10 transitions
Drop transitions (Empty/Sink Transition effects.) removed 5 transitions
Reduce isomorphic transitions removed 5 transitions.
Iterating post reduction 0 with 5 rules applied. Total rules applied 6 place count 15 transition count 20
Applied a total of 6 rules in 5 ms. Remains 15 /25 variables (removed 10) and now considering 20/35 (removed 15) transitions.
