Left-sorted BPs have the keyword "noisy" on the OEBP. Right-sorted examples have the keyword "minimal."

Noisy Bongard Problems include extra details varying between examples that distract from the solution property; more specifically noise is properties independent of the solution property that vary between examples. Minimalist Bongard Problems only vary details absolutely necessary to communicate the solution.

"Noisy" is different than the kind of distraction mentioned at distractingworld, which means the class of examples is distractingly specific, irrelevant to the solution, rather than that there are extra distracting properties changing between examples.

Bongard Problems have varying degrees of noisiness. Only include here BPs that are very noisy or very minimal.

See BP827 for the version with pictures of Bongard Problems (miniproblems) instead of links to pages on the OEBP.

See BP845 for noise in sequences of quantity increase.

Left-sorted problems have the keyword "finishedexamples" on the OEBP.

The addition does not have to be slight.

Left-sorted Problems usually have a very specific collection of examples, where the only images sorted all show the same type of object.

Any Bongard Problem where all examples are one shape outline will be sorted left, and (almost) any Bongard Problem where all examples are one fill shape will be sorted right.

See BP1144 for the version about both additions and erasures, and only slight changes are considered.

See BP1167 for a stricter version, the condition that all examples have the same amount of black and white.
