| π-演算采用互模拟作为进程等价的准则.对有限状态的π-演算进程互模拟等价是可判定的,由此提出了互模拟检测算法的一种优化技术.该技术基于只将输入名字实例化为在以后的等名测试中用到的自由名字.通过实例说明这一优化技术可大大减少所用的时间和空间,并证明了优化算法的正确性. |

| Abstract: |
| Bisimulation is adopted in the π-calculus as the criterion to identify processes. For finite-state processes, bisimulation equivalence is decidable. In this paper, an optimization technique for a bisimulation checking algorithm is presented. It works by instantiating input names only to those free names which are used in subsequent matches. The technique can significantly reduce the required time and space, as illustrated by several benchmark examples. The correctness of the optimization is also proven. |
