COMMENTS
|
Note if any point is contained in some smaller version of the whole, then any point is contained in arbitrarily smaller versions of the whole.
It isn't possible to unambiguously communicate in a picture whether or not a few specific points are included in the fractal. The pictures are interpreted as what is intuitively simplest. To make matters less ambiguous, all the fractals here contain all points arbitrarily close to points in them. (They are topologically closed. See also BP1239.)
The left hand side of this is a stronger condition than the left hand side of BP1116. |

BP1243 |
| Bongard Problems on the OEBP with certain examples that have not yet been proved to fit where they are currently sorted vs. Bongard Problems in which all included examples have been proved to fit where they are. |

COMMENTS

Bongard Problems sorted left have the keyword "missingproofs" on the OEBP.
This is an administrative keyword to help us keep track of what Bongard Problems we still need to check for correctness.
The description should indicate which examples are still in need of checking. Once proofs are found, the keyword "missingproofs" can be removed.
The keyword noproofs is similar. The difference is whether we want/expect to find proofs. |
