Timelock, time-divergence and Zenoness
· A path is time-divergent if its execution time is infinite
ExecTime(s0

i=0
di =
· TA is timelock-free if no state in Reach(TS(TA)) contains a timelock
a state contains a timelock whenever no time-divergent paths emanate from it
· TA is non-Zeno if there does not exist an initial Zeno path in TS(TA)
