Clarify Mutex Object and its use
Clarify Mutex Object and why it is employed?
Expert
A mutex object is a synchronization object whose state is set at signaled whereas it is not owned through any thread, & non-signaled while it is owned. For instance, to prevent two threads from writing to shared memory at the similar time, each thread waits for ownership of a mutex object before executing the code which accesses the memory. After writing to the shared memory, the thread releases the mutex object.
The following assertion types are part of PbC: Pre-condition: An assertion checked before a function/method body is executed. <

Understanding Property Violations: When a property violation is detected by the model checker, the model checker typically generates a counterexample trace. The trace points to the location where the violation was detected, but quite often what is rep
Model Checking a Program: The operation of a model checker can be described in terms of the familiar metaphor of searching a graph (Figure shown below). The nodes of the graph represent the states of the program and the links connecting the nodes repr
Search Strategies in model checking: Model checkers such as JPF and SPIN support a number of search strategies used to explore the state space of the program. Two of these strategies are the most well-known—Depth-First Search an
Explain the Support for Programming by Contract or pbc?
Uses of Programming by Contract: Contracts can also be used for dynamic, temporal properties (Mehlitz and Penix 2005), which are especially useful to verify protocol compliance (for instance, requiring the test state to keep track of previous evaluati
