WebSymbolic execution is a software testing technique that is useful to aid the generation of test data and in proving the program quality. Steps to use Symbolic Execution: The … WebMay 26, 2024 · During program traversing, symbolic execution collects path conditions and feeds them to a constraint solver to obtain feasible solutions. However, complex path conditions, like nonlinear constraints, which widely appear in programs, are hard to be handled efficiently by the existing solvers. In this paper, we adapt the classical symbolic …

The number of feasible paths in a program grows exponentially with an increase in program size and can even be infinite in the case of programs with unbounded loop iterations.
