BP831 Image of a Bongard Problem with left side having two rules and right side narrowing it down vs. image of Bongard Problem whose right hand side adds no information.
(edit; present; nest [left/right]; search; history)
COMMENTS

Right examples are Bongard Problems in which the left hand side is enough to communicate the full answer.


No examples shown have right side with multiple rules and left side narrowing down the answer.

BP832 Image of a Bongard Problem with solution presence of a specific object vs. image of a Bongard Problem with solution presence of a type of object.
(edit; present; nest [left/right]; search; history)
COMMENTS

"Specific object" we mean the same connected figure (up to movement around the box). It is ambiguous whether a scaled, rotated, or reflected version of an object would be considered "the same object" because no examples on either side are forced to deal with that subtlety in their respective solutions.

BP834 Image of a Bongard Problem such that the bottom left box rules out a solution vs. no single box affects the solution.
(edit; present; nest [left/right]; search; history)
COMMENTS

When removal of a box changes the solution, it cannot remove the existing solution; it can only allow more possible new solutions. Conversely, adding boxes can only narrow down between existing solutions.


The special box is always placed in the bottom left for help, but another solution is "there is some box whose removal allows another solution vs. not".


Bongard Problems sorted left might be called "deceptive". Especially when the solution ruled out by the one box is the more obvious solution.

BP835 Image of a Bongard Problem with solution about tiling vs. not so.
(edit; present; nest [left/right]; search; history)
COMMENTS

"Tiling" is placing shapes next to each other without overlap to fill up space or other shapes.

BP836 Image of a Bongard Problem with solution about a geometrical symmetry (invariance under spatial transformation) vs. not so.
(edit; present; nest [left/right]; search; history)
COMMENTS

Every Bongard Problem on the left shows invariance under some transformation in left sub-examples.


Some Bongard Problems on the right are symmetrical or have sub-examples that are symmetrical.

An image of this Bongard Problem would fit on the left.
