Although since he was the sole author of that paper, his Erdös number is still +∞. ]]>

This arxiv paper makes a connection to the size of objects in a search space and their symmetries: https://arxiv.org/abs/1412.6621. It’s also like Markov chains stopped prematurely. Maybe you’d like it.

]]>I believe Radford is completely correct here.

This is a fiction which one can argue has a correct representation (unlike with realities) and hence by deduction one and only one result. If the fiction is vague enough for k correct representations, then k results, if too vague for any representations then no results.

The never endingness I believe comes from folks trying to bring abduction or qualitative inference to bear on the fiction. Those are only appropriate for discerning an adequate representation. Once one has that, its just deduction.

By the way, I believe I arrived at the same position, using if you wish ABC where the outcome observed by Sleeping Beauty is compatible with any outcome observed – no rejections – http://stats.stackexchange.com/revisions/53ededf8-7610-4a99-b110-def80a083737/view-source
