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

The following Tetris pieces are placed on the grid:

- One "L" shaped piece ("rightl0") occupies positions: f2-0f, f3-0f, f3-1f.
- Three straight two-square pieces:
  - "straight0" occupies positions: f0-0f, f1-0f.
  - "straight1" occupies positions: f0-2f, f1-2f.
  - "straight2" occupies positions: f1-1f, f2-1f.
- Two single-square pieces:
  - "square0" occupies position: f0-1f.
  - "square1" occupies position: f2-2f.

Child State ID: 1
Action Taken: move_l_down(rightl0, f2-0f, f3-0f, f3-1f, f4-0f, f4-1f)
State Description: - **rightl0 (L-shaped piece)**: Now occupies positions f3-0f, f4-0f, and f4-1f. It has moved down, clearing its previous positions.- **straight0 (Two-square straight piece)**: Remains in positions f0-0f and f1-0f.- **straight1 (Two-square straight piece)**: Remains in positions f0-2f and f1-2f.- **straight2 (Two-square straight piece)**: Remains in positions f1-1f and f2-1f.- **square0 (One-square piece)**: Remains in position f0-1f.- **square1 (One-square piece)**: Remains in position f2-2f.- **Grid Cells (Unoccupied)**: Positions f5-0f to f5-3f, f4-2f to f4-3f, f3-2f to f3-3f, f2-0f, f2-3f, f1-3f, f0-3f are clear.
