There was also concern that BZs were abused or misused, caused addiction with difficult withdr...

Limit complexities revisited [once more]

The main goal of this article is to put some known results in a common perspective and to simplify their proofs. We start with a simple proof of a result of Vereshchagin [13] saying that limsupnC(x|n) (here C(x|n) is conditional (plain) Kolmogorov complexity of x when n is known) equals C0 ′ (x), the plain Kolmogorov complexity with 0′-oracle. Then we use the same argument to prove similar resu...
