COMMENTS

This is the final problem in Bongard's original collection. It is the only member of the collection that makes reference to human culture. This can be interpreted symbolically as foreshadowing that computers will be able to perform the various tasks that humans can do.
Another idea introduced by this Bongard Problem is that a Bongard Problem can teach its solution to the solver. (See keyword teach.) A large pool of examples can be used for training, as is common in machine learning. |

COMMENTS

Explanation / justification of BP229 by its creator:
"Long (doubly sized) objects are purines (A & G).
Short objects are pyrimidines (C & T).
Black are those forming triple Hbond (G and C).
White are those forming double Hbond (A & T).
On the left we have matching codes, i.e., bases, doublets or triplets that, when rotated, can pair correctly (A with T, G with C), binding the two strands.
On the right we have objects that no matter how they are rotated they do not pair correctly (because of bumps, wrong color codes, etc)." |
