Reducing state space of code

What is the way to reduce the state space of the code during model checking?

Verified

One way to dramatically reduce the state space of this code during model checking is to:

A) Replace the time variables with non-deterministic choices (e.g., a simple integer whose value can becontrolled by the model checker and possibly kept to a restricted range), and

B) ?Replace all time comparisons with a simple non-deterministic Boolean choice.

The problem with doing this across the entire program is that it may involve modifications to many parts of the code—everywhere the corresponding variable has been used or referenced. This is a time-consuming task for realistic systems and is error-prone.
