BP1075 Bongard Problem is the beginning of a chain of meta Bongard Problems containing meta Bongard Problems on the left side that eventually ends in BP1 vs. not so.

COMMENTS

This is an example of a meta Bongard Problem that sorts itself left, and would still sort itself left after the sides in the title were switched.

That is, this BP is tagged the keyword left-self and so would its flipped version be.

CROSSREFS

See also the keyword feedback for chains of meta Bongard Problems that eventually form loops.

COMMENTS

Left examples have the keyword "feedback" on the OEBP.

CROSSREFS

"Feedback" implies not wellfounded.

Left-it" or right-it implies "feedback".

COMMENTS

This is the "it" Problem.


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

Right-sorted Bongard Problems have the keyword "right-it" on the OEBP.

CROSSREFS

Left-it or right-it implies feedback.
