Current State ID: 0
Current State Description: This initial state describes a Tetris puzzle on a 6-row by 4-column grid. Positions are named by their row and column (e.g., f0-0f is row 0, column 0). Positions are connected horizontally and vertically to their immediate neighbors.

Initially, the following positions are clear (empty and available for pieces to move into):

- Row 0: f0-0f, f0-3f
- Row 1: f1-3f
- Row 2: f2-1f, f2-3f
- Row 3: f3-0f, f3-1f
- Row 4: f4-0f, f4-1f, f4-2f, f4-3f
- Row 5: f5-0f, f5-1f, f5-2f, f5-3f

The following Tetris pieces are placed on the grid:

- One "L" shaped piece ("rightl0") occupies positions: f2-2f, f3-2f, f3-3f.
- Two straight two-square pieces:
  - "straight0" occupies positions: f0-1f, f1-1f.
  - "straight1" occupies positions: f0-2f, f1-2f.
- Two single-square pieces:
  - "square0" occupies position: f1-0f.
  - "square1" occupies position: f2-0f.

Child State ID: 1
Action Taken: move_two(straight0, f0-1f, f1-1f, f2-1f)
State Description: - **rightl0 (L-shaped piece)**: Occupies positions f2-2f, f3-2f, and f3-3f. Status: unchanged.- **straight0 (Two-square straight piece)**: Now occupies positions f1-1f and f2-1f. Status: moved down.- **straight1 (Two-square straight piece)**: Occupies positions f0-2f and f1-2f. Status: unchanged.- **square0 (One-square piece)**: Occupies position f1-0f. Status: unchanged.- **square1 (One-square piece)**: Occupies position f2-0f. Status: unchanged.- **Grid Cells (Unoccupied)**: Positions f0-0f, f0-1f, f0-3f, f1-3f, f2-3f, f3-0f, f3-1f, f4-0f to f4-3f, f5-0f to f5-3f are clear. Position f0-1f is now clear.

Child State ID: 3
Action Taken: move_l_down(rightl0, f2-2f, f3-2f, f3-3f, f4-2f, f4-3f)
State Description: - **rightl0 (L-shaped piece):** Moved down to occupy positions f3-2f, f4-2f, and f4-3f, colored blue.- **straight0 (Two-square straight piece):** Remains in positions f0-1f and f1-1f, colored green.- **straight1 (Two-square straight piece):** Remains in positions f0-2f and f1-2f, colored red.- **square0 (One-square piece):** Remains in position f1-0f, colored yellow.- **square1 (One-square piece):** Remains in position f2-0f, colored orange.- **Grid Cells (Unoccupied):** Positions f0-0f, f0-3f, f1-3f, f2-1f, f2-2f, f2-3f, f3-0f, f3-1f remain clear. New clear positions are f3-3f.
