COMMENTS

Rhetorical question: Where does this Bongard Problem sort an image of itself?

See BP999 and BP1004 for similar paradoxes.

See BP517 for the version with links to pages on the OEBP instead of images of Bongard Problems (miniproblems).

COMMENTS

"BONGARD HELL."

This the flipped version of BP793 but using only images of Bongard Problems with solution "__ half more black/less white than other half versus vice versa," that all use rotated, reflected, and inverted versions of the same examples.

CROSSREFS

See BP971 (left vs. right more black) and BP972 (top vs. bottom more black).

BP830 Image of a Bongard Problem with left side a "positive" property and right side the "negative" property versus vice versa.
(edit; present; nest [left/right]; search; history)
COMMENTS

Left: the left hand side is enough to communicate the answer; the left pattern can be seen without the counterexamples on the right.

Right: the right hand side is enough to communicate the answer; the right pattern can be seen without counterexamples on the left.


Flipping a BP will switch its sorting.


The following is taken from the comments on page BP513 (keyword left-narrow):

Call a pattern "narrow" if it is likely to be noticed in a collection of examples, without any counterexamples provided.

A collection of triangles will be recognized as such; "triangles" is a narrow pattern. A collection of non-triangular shapes will just be seen as "shapes"; "not triangles" is not narrow.

Narrow patterns tend to be phrased positively ("is [property]"), while non-narrow patterns opposite narrow patterns tend to be phrased negatively ("is not [property]").

CROSSREFS

See keywords left-narrow and right-narrow.

BP881 Right pattern is "part of" left pattern (proper subset) vs. right pattern is not subset of left pattern.
(edit; present; nest [left/right]; search; history)
COMMENTS

No one object is included on both sides of a dividing line in any example. Left examples when seen as Bongard Problems may either read as "not [right pattern] vs. [right pattern]" or have no unconvoluted solution at all, depending on whether the left side includes any objects that would fit in with the right side.
