The paper lacks an experimental results section. So I don't know how this simplicity measure compares to Solomonoff induction.
The paper does discuss some simplicity measures, but it is more like a framework
for combining simplicity measures.
Distributions that favor fast programs are allowed but not favored by Occam's Razor. We only use them because of practical limitations. But we still believe that a multiverse is more likely than a universe because it is a simpler description of our observations, in spite of requiring more physics computation.
It is, I think a widespread criticism of multiverse theories that they require more compute. WIth our physics, runtime is frequently penalized - but if the visible universe is part of a much bigger world different physical laws might hold there. Maybe there runtime is heavily penalized - or maybe it is not. We don't really know. Anyway, we have evidence supporting a multiverse from interference experiments. Occam's razor is all about priors. Once data starts to flood in, priors diminish in significance and are often soon swamped. -- __________ |im |yler http://timtyler.org/
