| Outline of Final Research Achievements |
We have developed techniques for verifying various properties (e.g., safety and stability) about hybrid systems that involve continuous and discrete behaviors, using interval constraint programming and deductive reasoning. Development of this research is based on the notion of constraints that integrates reliable numerical computation and symbolic computation (e.g., formula manipulation and temporal logic verification). We have built (i) a parallel interval constraint solver that handles efficiently nonlinear arithmetic constraints, and (ii) a verifier for hybrid systems based on the constraint solver. In the experiments, we have shown that several models, which are difficult to handle with existing tools, can be verified with our tools.
