一句话:为可靠确定型协商提出两种主动学习算法,利用其结构实现最小化,查询复杂度与协商规模多项式相关。
论文研究可靠确定型协商(sound deterministic negotiations)的主动学习问题。这类模型可视为带额外结构的 Petri 网或 Zielonka 自动机,用于描述分布式系统。作者首先证明该额外结构使得此类协商可以被最小化。在此基础上,提出两种主动学习算法,区别在于所使用的成员查询类型。两种算法的复杂度均与 Angluin 的 L* 算法类似,查询数量是协商规模的多项式,而非其配置数的多项式。
We present two active learning algorithms for sound deterministic negotiations. Sound deterministic negotiations are models of distributed systems, a kind of Petri nets or Zielonka automata with additional structure. We show that this additional structure allows to minimize such negotiations. The two active learning algorithms differ in the type of membership queries they use. Both have similar complexity to Angluin’s L* algorithm, in particular, the number of queries is polynomial in the size of the negotiation, and not in the number of configurations.
