The user wants me to synthesize the observations from the three examples and refine the natural language program. I need to make sure the program works for all examples.

Example 1: Non-white pixels move to the bottom row, ordered by their original column. Example 2: Non-white pixels not part of the yellow or orange blocks move to the bottom row, ordered by their original column. The yellow and orange blocks stay in place. Example 3: All non-white pixels move to the bottom rows of their original columns.

The rule from Example 3 seems to be the most general and covers the observations in Example 1. Let’s test if it fits Example 2.

In Example 2:

Yellow pixels in column 0 go to the bottom of column 0.
Maroon pixel in column 5 goes to the bottom of column 5.
Azure pixels in column 3 go to the bottom of column 3.
Orange pixels in column 2 go to the bottom of column 2.

This fits the “fall down” rule.

Let’s refine the natural language program based on this.

Summary of Observations:

Across all three examples, the transformation appears to involve moving the non-white pixels towards the bottom of the grid, within their respective columns.

Example 1: All non-white pixels shift to the last row, maintaining the order based on their original column position.
Example 2: All non-white pixels shift downwards within their columns. The contiguous blocks of yellow and orange pixels also follow this rule.
Example 3: All non-white pixels shift downwards within their respective columns.

The consistent pattern observed is that non-white pixels move towards the bottom of the grid, staying within their original columns.

Code Re-investigation:

Let’s write a function to simulate the “falling down” of pixels and test it against the examples.

import numpy as np

def apply_transformation(input_grid):
    height, width = input_grid.shape
    output_grid = np.zeros_like(input_grid)
    for col in range(width):
        non_white_pixels = [input_grid[row, col] for row in range(height) if input_grid[row, col] != 0]
        num_non_white = len(non_white_pixels)
        for i in range(num_non_white):
            output_grid[height - num_non_white + i, col] = non_white_pixels[i]
    return output_grid

# Example 1
input_grid_1 = np.array([[0, 4, 0, 9],
                         [0, 0, 0, 0],
                         [0, 4, 6, 0],
                         [1, 0, 0, 0]])
output_grid_1 = np.array([[0, 0, 0, 0],
                          [0, 0, 0, 0],
                          [0, 4, 0, 0],
                          [1, 4, 6, 9]])
predicted_output_1 = apply_transformation(input_grid_1)
print("Example 1 Prediction Correct:", np.array_equal(predicted_output_1, output_grid_1))

# Example 2
input_grid_2 = np.array([[0, 0, 0, 0, 0, 9],
                         [0, 0, 0, 8, 0, 0],
                         [0, 0, 0, 0, 0, 0],
                         [4, 0, 0, 0, 0, 0],
                         [4, 0, 7, 8, 0, 0],
                         [4, 0, 7, 0, 0, 0]])
output_grid_2 = np.array([[0, 0, 0, 0, 0, 0],
                          [0, 0, 0, 0, 0, 0],
                          [0, 0, 0, 0, 0, 0],
                          [4, 0, 0, 0, 0, 0],
                          [4, 0, 7, 8, 0, 0],
                          [4, 0, 7, 8, 0, 9]])
predicted_output_2 = apply_transformation(input_grid_2)
print("Example 2 Prediction Correct:", np.array_equal(predicted_output_2, output_grid_2))

# Example 3
input_grid_3 = np.array([[0, 0, 0, 1, 0],
                         [0, 3, 0, 0, 0],
                         [0, 3, 0, 1, 2],
                         [6, 0, 0, 0, 0],
                         [0, 3, 0, 0, 0]])
output_grid_3 = np.array([[0, 0, 0, 0, 0],
                          [0, 0, 0, 0, 0],
                          [0, 3, 0, 0, 0],
                          [0, 3, 0, 1, 0],
                          [6, 3, 0, 1, 2]])
predicted_output_3 = apply_transformation(input_grid_3)
print("Example 3 Prediction Correct:", np.array_equal(predicted_output_3, output_grid_3))

The code confirms that the “falling down” transformation works correctly for all three examples.

Final Natural Language Program:

Context: The input is a grid containing pixels of various colors, including white.

Process:

Initialize an empty output grid of the same dimensions as the input grid, filled with white pixels.
Iterate through each column of the input grid from left to right.
Within the current column, identify all non-white pixels and their colors, preserving their original order from top to bottom.
Place these identified non-white pixels into the corresponding column of the output grid, starting from the bottom row and filling upwards. The topmost non-white pixel from the input column should be placed in the highest available empty cell (from the bottom) in the output column.
After processing all columns, the output grid will represent the transformed input grid.
