Running 0 sub problems to find dead transitions.
Search for dead transitions found 0 dead transitions in 0ms
Starting structural reductions in LIVENESS mode, iteration 1 : 0/4030 places, 1/4020 transitions.
Finished structural reductions in LIVENESS mode , in 1 iterations and 98 ms. Remains : 0/4030 places, 1/4020 transitions.
Net is quasi-live, checking if it is reversible to establish liveness.
Net is conservative; using simplified expression for initial state.
Able to resolve query Liveness after proving 1 properties.
