BP1127

There is no rule for how the objects in a cluster interrelate vs. there is.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`Other ways of phrasing this:` `"Local" vs. "global" properties of collections: to check a collection satisfies a "local" property, it is only necessary to check each individual thing in it satisfies some property.` `The rule all collections satisfy is just "every object is a ___" vs. the rule is something more.`

	KEYWORD	`abstract, creativeexamples, left-unknowable, rules, miniworlds`

BP1153

Valid multi-sided Bongard Problems vs. invalid multi-sided Bongard Problems.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`This is a generalisation of Bongard Problems that allows them to have any number of sides. There is a sense in which this problem is about valid vs. invalid ways of partitioning a set of examples into equivalence classes.`

BP1155

Shapes are sorted according to a simple rule that uniquely determines where everything goes vs. shapes are sorted according to some other rule (or lack thereof).

BP1157

The order in which the objects in the top half are combined to make the object in the lower half matters vs. not so.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`Operations depicted in right-sorted examples are called "commutative".` `"Order matters" here means that if the objects in the top half were to switch places, the output would look different.`

BP1191

One natural way of matching up the two collections vs. multiple natural ways of matching up the two collections.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`Jago originally designed this as a triptych. EX9655, EX9656, and EX9657 belong in a third category displayed further right of the two categories shown here. The third category is "all possible ways of matching are equally natural". - Aaron David Fairbanks, Apr 18 2022`
