| Outline of Final Research Achievements |
We have studied a method to verify comprehensive safety of software by using backward simulation. Specifically, we realized a method of detecting bugs in programs and malfunction factors while sequentially executing bytecodes corresponding to machine language for Java programs in the backward direction. We have tried a numerical range division method and a symbolic analysis method as the backward execution method, and obtained knowledges about characteristics of each methods.
