查询词典 Roche limit

To study the limit behavior of computations, the procedure scheme (Li, 1992, 1999) is generalized to model convergent infinite computations for analyzing how an infinite computation interacts and evolves in changing environments and what the limit of the evolution might be. The model is based on classical computation model Turing machine and Li's limit theory of sequences of formal systems.
