COMMENTS

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


Sometimes all the examples in a Bongard Problem need to be interpreted a certain way for the Bongard Problem to make sense. Only once the representation is understood, the idea seems simple.


For example, all meta Bongard Problems (Bongard Problems sorting other Bongard Problems) assume the solver interprets the examples as Bongard Problems.


TO DO: Maybe it is best to stop putting the label "assumesfamiliarity" on all meta-Bongard Problems. There are so many of them. It may be better to only use the "assumesfamiliarity" keyword on meta-BPs for a further assumption than just that all examples are interpreted as Bongard Problems. - Aaron David Fairbanks, Feb 11 2021

CROSSREFS

Many Bongard Problems in which all examples take the same format (keyword structure) assume the solver already knows how to read that format.

Some Bongard Problems assume the solver will be able to understand symbolism that is consistent between examples (keyword consistentsymbols).

Bongard Problems tagged math often assume the solver is familiar with a certain representation of a math idea.

EXAMPLE

BP1032: The solution should really read "Assuming all images are Bongard Problems sorting each natural number left or right ..." This Bongard Problem makes sense to someone who has been solving a series of similar BPs, but otherwise there is no reason to automatically read a collection of numbers as standing for a larger collection of numbers.

COMMENTS

Bongard Problems sorted left have the keyword "links" on the OEBP.

Bongard Problems sorted right have the keyword "miniproblems" on the OEBP.


The keyword "links" is automatically added to a Bongard Problem on the OEBP if a BP number is added as an example.


Meta Bongard problems that sort Bongard Problems purely based on their solutions (keyword presentationmatters) usually have two versions in the database: one that sorts images of Bongard Problems and one that sorts links to pages on the OEBP. If both versions exist, users should make them cross-reference one another.

CROSSREFS

All the examples of miniature Bongard Problems within any meta Bongard Problem tagged "miniproblems" would fit left on BP1080 (which is a showcase of the various formats for images of Bongard Problems).

COMMENTS

Bongard Problems sorted left have the keyword "inductivedefinition" on the OEBP.


An inductive definition is like, "Call certain basic objects 'blurps', and call combinations of blurps 'blurps' too."

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.
