Mikkel Hansen, Kim Guldstrand Larsen, Radu Mardare, Mathias Ruggaard Pedersen

AI总结:

本文提出一种推理加权转移系统中转移权重界限的方法,引入更粗的互模拟概念,并设计定制模态逻辑,证明其不变性、有限模型性质、完备公理化及可判定性。

摘要:

我们提出了一种推理加权转移系统(WTS)中转移权重的最小值和最大值的方法。这一视角引出了一种比经典互模拟更粗的互模拟概念:它关联那些展现出转移到互模拟类且权重在相同边界内的状态。我们提出了一种定制的模态逻辑,通过特定的模态词来表达转移权重的数值边界。我们证明了我们的逻辑在所提出的互模拟概念下是不变的。我们展示了该逻辑具有有限模型性质,并为其确定了一个完备的公理化。最后但同样重要的是,我们使用tableau方法证明了该逻辑的可满足性问题是可判定的。

英文摘要:

We propose a way of reasoning about minimal and maximal values of the weights of transitions in a weighted transition system (WTS). This perspective induces a notion of bisimulation that is coarser than the classic bisimulation: it relates states that exhibit transitions to bisimulation classes with the weights within the same boundaries. We propose a customized modal logic that expresses these numeric boundaries for transition weights by means of particular modalities. We prove that our logic is invariant under the proposed notion of bisimulation. We show that the logic enjoys the finite model property and we identify a complete axiomatization for the logic. Last but not least, we use a tableau method to show that the satisfiability problem for the logic is decidable.
