Most visual BPs will be sorted left by this problem, as examples usually have white backgrounds by default.

COMMENTS

Left-sorted Bongard Problems have the keyword "problemkiller" on the OEBP.


An example could be unsortable because it does not conform to the format of all the examples in the Bongard Problem, or it could be formatted like the other examples but be treated ambiguously by the solution. It seems the Bongard Problems currently labeled "problemkiller" mostly deal with examples becoming unsortable because they no longer conform to the format. (The examples become unsortable because they leave the "world" of the Bongard Problem. See https://www.oebp.org/world.php .) - Aaron David Fairbanks, Jun 15 2023

CROSSREFS

"Problemkiller" Bongard Problems are notso Bongard Problems.


See keyword invariance, which is about transformations making some example switch sides rather than transformations making all examples unsortable.
