Few mathematical constructs seem as conceptually simple as that of randomness.
很少有数学结构在概念上像随机性那样简单。
So far, machines have a pretty hard time emulating creativity, arbitrary enough not to be predicted by a computer, and yet more than simple randomness.
This unwelcome result prompts Chaitin and Kolmogorov to suggest the need for a new standard of randomness, one that relies on the internal coherence of the set as opposed to its origin.
