在本文中,我们研究算法的随机性更一般的空间比康托空间,即可计算度量空间。要做到这一点,我们首先开发一个统一的框架,允许计算的概率措施。我们表明,任何可计算的度量空间与可计算的概率测度同构的康托空间在可计算和测量理论的意义。我们表明,任何可计算的度量空间承认一个普遍的一致随机性测试(没有进一步的假设)。
In this paper, we investigate algorithmic randomness on more general spaces than the Cantor space, namely computable metric spaces. To do this, we first develop a unified framework allowing computations with probability measures. We show that any computable metric space with a computable probability measure is isomorphic to the Cantor space in a computable and measure-theoretic sense. We show that any computable metric space admits a universal uniform randomness test (without further assumption).
