Current structural bounds on expressions (After Parikh guided walk) : Max Seen:[] Max Struct:[]
RANDOM walk for 0 steps (0 resets) in 4 ms. (0 steps per ms) remains 0/0 properties
Finished probabilistic random walk after 0 steps, run visited all 0 properties in 0 ms. (steps per millisecond=0 )
Current structural bounds on expressions (After reachability solving 0 queries.) : Max Seen:[] Max Struct:[]
All properties solved without resorting to model-checking.
Total runtime 69425 ms.
ITS solved all properties within timeout
