fications. We do not yet know how to check properties specified using nondeterministic
timed automata or using linear real­time logics.
The algorithm outlined here is expensive. To make it more practical, some heuris­
tic techniques need to be devised. Observe that the verification problems are typically
PSPACE, even in the absence of real­time and probabilities. We feel hopeful that the
