概率异步pi演算

Probabilistic asynchronous pi-calculus

Oltea Mihaela Herescu, Catuscia Palamidessi

摘要:

我们提出了一个扩展的异步π演算的随机选择的概念。我们定义了一个操作语义,区分概率的选择,内部的进程,和不确定性的选择,外部的对手调度。这种区别将使我们能够推理算法在特定条件下的概率正确性。我们表明,在这种语言中,我们可以解决的选举问题,这被证明是不可能的异步$π$演算。最后,我们展示了一个实现的概率异步π演算在一个类似Java的语言。

英文摘要:

We propose an extension of the asynchronous pi-calculus with a notion of random choice. We define an operational semantics which distinguishes between probabilistic choice, made internally by the process, and nondeterministic choice, made externally by an adversary scheduler. This distinction will allow us to reason about the probabilistic correctness of algorithms under certain schedulers. We show that in this language we can solve the electoral problem, which was proved not possible in the asynchronous $π$-calculus. Finally, we show an implementation of the probabilistic asynchronous pi-calculus in a Java-like language.
