Reducing state space of code
What is the way to reduce the state space of the code during model checking?
Expert
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.
Use Finite-State Space Abstractions: In order to successfully apply explicit-state model checking, defects must be detectable in a sufficiently small state space. This can be achieved either by means of heuristics that constrain the way the state spac
Synchronized statement: It is a statement in which an object-lock should be obtained for the target object prior to the body of the statement and can be entered. Employed to enclose a critical section in order to save a race hazard.
Loop variable: A variable employed to control the operation of a loop, like a for loop. Usually, a loop variable will be provided an initial value and it is then incremented after each and every iteration till it passes or reaches a terminating value.

Inheritance hierarchy: The relationship among super-classes and sub-classes is termed as an inheritance hierarchy. The single inheritance of classes means that each and every class has simply a single `parent' class and that Object class is the eventu
Primitive Type Abstractions: An effective way to reduce the state space of a program is to replace the primitive types with the corresponding abstractions that encapsulate all the possible operations that are performed on these types.
