Software systems can exhibit massive numbers of execution paths, and even comprehensive testing can exercise only a small fraction of these. It is no surprise that systems experience errors and vulnerabilities in use when many executions are untested. Computations over the functional semantics of programs may offer a potential solution. Structured programs are expressed in a finite hierarchy of control...
Automated software behavior computation is an emerging technology under development at the Software Engineering Institute that can be applied to analysis of malicious code. Behavior computation is based on the semantics of programming language instructions and the opportunity to compose them to determine net effects of programs. An initial implementation is targeted to malicious code expressed in...
Next-generation software engineering is envisioned as a computational discipline that complements human capability through automated computation of software behavior and properties to the maximum extent possible. To help realize this vision, we are exploring the technology of function extraction. Behavior computation for sequences and alternations is relatively straightforward, but no general theory...
The ultra-large-scale systems of the future require the transformation of software engineering into a computational discipline capable of fast and dependable software development. This paper discusses an emerging next-generation software engineering research area: function extraction (FX) technology for automated computation to the maximum extent possible of the behavior, correctness, and quality...
