Search for dead transitions found 4 dead transitions in 227ms
Found 4 dead transitions using SMT.
Drop transitions (Dead Transitions using SMT only with invariants) removed 4 transitions
Dead transitions reduction (with SMT) removed 4 transitions
Starting structural reductions in SI_LTL mode, iteration 1 : 20/21 places, 13/18 transitions.
Graph (complete) has 21 edges and 20 vertex of which 16 are kept as prefixes of interest. Removing 4 places using SCC suffix rule.1 ms
Discarding 4 places :
Also discarding 0 output transitions
Applied a total of 1 rules in 6 ms. Remains 16 /20 variables (removed 4) and now considering 13/13 (removed 0) transitions.
