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

Right-sorted Bongard Problems have the keyword "less." They are not necessarily "bad," but we do not want more like them.

Left examples are not required to be valid, as long as their solution doesn't apply in the traditional Bongard Problem format (6 panels vs. 6 panels, all one image). Additionally, they do not necessarily have to be rendered invalid by being viewed in the template format, but their solution does have to be altered. In some cases left examples are simply Problems whose solution is specific to the computer medium (BP941), however some examples have more profound solutions that the pen-and-paper template medium is too restrictive to represent (BP854).

See BP568.

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.

Left-it or right-it implies feedback.

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

This is an administrative keyword to help us keep track of what Bongard Problems we still need to check for correctness.

The description should indicate which examples are still in need of checking. Once proofs are found, the keyword "missingproofs" can be removed.

The keyword noproofs is similar. The difference is whether we want/expect to find proofs.

Bongard Problems tagged "missingproofs" should necessarily be hardsort.
