Bongard Problems whose "world" is Bongard Problems.
Bongard Problem solution ideas that sort Bongard Problem solution ideas (with no further restrictions).
Sometimes abbreviated MBPs.
This is the keyword "meta" on the OEBP.
Note that BP527 (Meta Meta BPs) are not Strictly Meta BPs because their "world" is restricted to a sub-class of the Meta BPs. We should have a separate BP page for Meta BPs of all layers of nesting.
Metaright-BPs cannot technically sort quantity-based BP Pages. A BP Page about a quantity represents a class of many Bongard Problems. A typical meta-BP should be able to sort "size less than five" but not "size." On the OEBP we include a quantity-based BP as a "left example" on a meta-BP's page if ALL the specific less-than-x versus greater-than-x Problems on the spectrum are left examples. Likewise we include it as a right example if ALL incarnations are right examples. Otherwise the quantity-based BP is ambiguously sorted by the meta-BP. |
