Kolmogorov complexity is the length of the ultimately compressed version of a file (i.e., anything which can be put in a computer). Formally, it is the length of a shortest program from which the file can be reconstructed. We discuss the incomputability of Kolmogorov complexity, which formal loopholes this leaves us with, recent approaches to compute or approximate Kolmogorov complexity, which approaches are problematic, and which approaches are viable.
柯尔莫哥洛夫复杂度是文件(即任何可存入计算机的内容)最终压缩版本的长度。形式上,它是能够重构该文件的最短程序的长度。我们将讨论柯尔莫哥洛夫复杂度的不可计算性、由此留下的形式漏洞、计算或近似柯尔莫哥洛夫复杂度的最新方法、哪些方法存在问题以及哪些方法可行。
