Kazuki Watanabe, Clovis Eberhart, Kazuyuki Asada, Ichiro Hasuo

AI总结:

本文利用幺半范畴与字符串图构建平均支付博弈的组合式求解框架,并以 Haskell 实现,在部分基准上较现有算法提速一个数量级。

摘要:

继我们最近为 Markov 决策过程开发了一种组合式模型检验算法之后,本文提出了一个用于求解平均支付博弈(MPGs)的组合式框架。该框架源自范畴论,特别是幺半范畴理论:MPGs(被扩展以包含开放端)在所谓的字符串图中被组合,从而组织在一个幺半范畴中;其求解随后被表示为一个函子,该函子的保持性质体现了组合性。与通常情况一样,组合性的关键问题是如何丰富语义域;范畴论框架通过识别扩展语义域所需的代数结构,为解决该问题提供了有依据的指导。我们在 Haskell 中实现了该组合式求解方法;根据基准测试的不同,其性能可以比现有算法高出一个数量级。

英文摘要:

Following our recent development of a compositional model checking algorithm for Markov decision processes, we present a compositional framework for solving mean payoff games (MPGs). The framework is derived from category theory, specifically that of monoidal categories: MPGs (extended with open ends) get composed in so-called string diagrams and thus organized in a monoidal category; their solution is then expressed as a functor, whose preservation properties embody compositionality. As usual, the key question to compositionality is how to enrich the semantic domain; the categorical framework gives an informed guidance in solving the question by singling out the algebraic structure required in the extended semantic domain. We implemented our compositional solution in Haskell; depending on benchmarks, it can outperform an existing algorithm by an order of magnitude.
