Participant 7

Initial description: Double the grid size. Put the input to the lower right of the output. Put a vertically flipped version of the input in the upper right. Put a horizontally flipped version of the input in the lower left. Then put an image of the input flipped horizontally and vertically in the upper left.

Final description: Output will be double the size of the input. Place the input in the lower right. Fill the upper right with a vertically-flipped version of the input. Fill the lower left with a horizontally-flipped version of the input. Fill the upper left with a version of the input that has been flipped vertically and horizontally.


Attempt 1: Incorrect
Attempt 2: Correct

Participant 8

Initial description: the grid size is doubled in each direction. the test input is copied to the lower right corner grid. It is then mirrored in each of the other corners of the grid.
