BP876 Precise sorting of potential examples vs. not so.
(edit; present; nest [left/right]; search; history)
COMMENTS

Left Bongard Problems do not have to sort all relevant examples; if they would leave some border cases unsorted, it just has to be clear precisely which examples those would be.


Often a precise divide between values on a spectrum comes from intuitively "crossing a threshold." For example, there is an intuitive threshold between acute and obtuse angles. Two sides of a Bongard Problem on opposite ends of a threshold, coming close to it, are interpreted as having precise divide between sides, right up against that threshold.

BP877 "Less than vs. greater than" (or vice versa) vs. "equal to vs. greater than" (or less than).
(edit; present; nest [left/right]; search; history)
COMMENTS

Left examples are quantity-comparison Problems in which the dividing point on the spectrum separating the sides lands between them. Right examples are quantity-comparison Problems in which the dividing point is the entirety of one of the sides (always the left side, for clarity).

Only less-than vs. greater-than Problems may have imprecise (BP876right) dividing point between sides.

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

You can try to interpret these images as Bongard Problems. This works just when the left side includes no objects that would fit in with the right side (as in EX7357 but not EX7361), the solution is "not [right pattern] vs. [right pattern]"; otherwise there is no apparent solution.


The solvable Bongard Problems sorted left here are right-narrow and not left-narrow, with the left side the negation of the right side (see notso).

BP894 Examples fit solution (once it is known) relatively obviously vs. examples fit solution in subtle or complex, harder-to-see ways.
(edit; present; nest [left/right]; search; history)
COMMENTS

One left and one right example with each solution are shown for help.


This BP is fuzzy for multiple reasons. How obvious it is that an example fits a rule is subjective. Also, somebody could read the simplicity of all included examples as part of a Bongard Problem's solution. For example, the more obvious version of "square number of dots vs. non-square number of dots" could be interpreted as "square small number of dots arranged in easy-to-read way vs. non-square small number of dots arranged in easy-to-read way."


Whether this Bongard Problem solution would categorize an image of itself left or right depends on the difficulty of the solutions of the mini-Problems.

BP968 Valid Bongard Problem vs. invalid Bongard Problem.
(edit; present; nest [left/right]; search; history)
COMMENTS

"Invalid Bongard Problems" are images that look sort of like Bongard Problems but aren't actually Bongard Problems.


With many examples included, this Problem might be placed somewhere to nonverbally show someone the subtler rules about what is allowed and what isn't allowed in Bongard Problems.


See BP829 for the Bongard Problem about Bongard Problems with no clear solution.

CROSSREFS

See BP522 (flipped) for a version with links to pages on the OEBP instead of images of Bongard Problems (miniproblems).


See BP829 (flipped) for a near exact copy of this Bongard Problem idea but that does not include images with two of the same boxes on either side.

Also see BP1080, which includes various different formats of Bongard Problems, distinguishing them from arbitrary images that are not Bongard Problems.
