                                    Summary                                     

I've successfully completed the Tower of Hanoi puzzle using Answer Set          
Programming with clingo. Here's what was accomplished:                          

                               Solution Overview                                

 • Total moves: 15 (optimal for 4 disks)                                        
 • Verification: ✓ All disks successfully moved from peg A to peg C             
 • Optimality: ✓ Achieves the theoretical minimum of 2^n - 1 = 15 moves         

                           Key Implementation Details                           

The ASP model follows the Sequential Planning Pattern with:                     

 1 State Representation: on_peg(Disk, Peg, Time) fluents track disk locations   
 2 Action Generation: Exactly one move per timestep from valid top disks        
 3 Constraints:                                                                 
    • Only top disks can be moved (no smaller disk above)                       
    • Larger disks cannot be placed on smaller disks                            
    • Disks cannot be in two places simultaneously                              
 4 Frame Axioms: Disks persist on their peg unless moved                        
 5 Goal: All disks on peg C at time 15                                          

The solution correctly produces a valid 15-move sequence that solves the puzzle 
optimally, with output formatted as the required JSON structure.
