prior is a recursive distribution. This idea of a universal probability distribution is an extremely
powerful result of this theory, but is beyond the scope of this chapter--for more information, see

2.6 HISTORICAL NOTES
The history of Kolmogorov complexity, or Algorithmic Information Theory, is quite interest-
ing. The same core principles were discovered independently by at least three different people
within the span of a few years. The convergence of results and ideas, in areas ranging from com-
putability to probability theory, made the emergence ...
