The paper researches on the complexity probability. The research on the complexity has been a prosperous discipline,which developed with the system theory, cybernetics and information theory. On huge numerical phenomenon and life-being's self-organization complexity has been a mature systematical scientific theory. It is now another key method for the understanding of the material world. The connections between mathematical model construction and the using of the probability method have been recognized.the probability theory is a main character for modern science,its generality and validity is no less than the complexity's. So the need for the further clarity of it is necessary work.According the above all, our research mainly comprises four parts. In the first chapter, we recall foundational conceptions as the background for the further interpretations, it emphasize the complexity phenomenon, the linguistic system, probability system and the differences between them。 The second chapter mainly researches on the simplicity and the complexity, through the example description. The third chapter, using metaphysical comparative analyzing shows us the probability as the understanding background for the simplicity deeds in the complexity system. The fourth chapter, closing.This paper is the difficulty of clarifying various concepts:there are mainly probability and the differences between simple phenomenon, complex phenomenon and random phenomena under complexity background. At present there are many books and essays about the study of philosophy and probability. However, from various kinds of material to mining the relationship between the complexity and probability is particularly difficult, so this paper is just a small try of the research direction, it will need to be further researches. |
