Example 1 of e1d2900e is self-inconsistent (one blue cell moves, another doesn't) #59
Description
The inferred rule of this task is:
- Each blue cell moves towards the closest red square to which it is horizontally or vertically aligned
However, in the following example, there is a blue cell that is horizontally aligned with the bottom-most red square,
yet it doesn't move:
Alternate, more complex rules could consider not to move cells if they are equally far from multiple red squares,
which is true for that particular blue cell if taking chebyshev distances; in that case, it would be equally far
from the red square roughly above it (to which it is not exactly aligned vertically, so no issue with the original rule).
However, that upper red square has another blue cell which is in the exact same relation to these two red rectangles,
symmetrically rotated by 180°. Because that blue cell does move, any rule would have to break rotational/inversion symmetry
to resolve the discrepancy. It is unlikely that this is intended, given that this situation doesn't arise in the test-case.
