                                    Summary                                     

I've successfully completed the Blocks World planning task using Answer Set     
Programming (ASP) with the clingo Python API.                                   

Solution Overview:                                                              

The optimal plan requires 3 moves to transform the initial configuration into   
the goal state:                                                                 

 1 Move C from A to table - Clears block A                                      
 2 Move B from table to C - Builds the B-on-C stack                             
 3 Move A from table to B - Completes the goal: A on B, B on C, C on table      

Key Implementation Details:                                                     

 • Fluents: Modeled state with on(Block, Location, Time) and clear(Block, Time) 
 • Actions: Single move action per timestep with proper preconditions (only     
   clear blocks can move)                                                       
 • Frame Axioms: Blocks persist in their locations unless explicitly moved      
 • State Exclusivity: Enforced that blocks can only be in one location at a time
 • Optimization: Used #minimize to find the shortest plan                       
 • Time Horizon: Set to 3 timesteps based on expected optimal length            

The solution correctly handles all constraints and produces the expected optimal
3-move plan.
