                                    Summary                                     

I've successfully solved the DONALD + GERALD = ROBERT cryptarithmetic puzzle    
using Answer Set Programming with the clingo Python API.                        

Solution Found:                                                                 

                                                                                
 {                                                                              
   "assignment": {                                                              
     "A": 4, "B": 3, "D": 5, "E": 9, "G": 1,                                    
     "L": 8, "N": 6, "O": 2, "R": 7, "T": 0                                     
   },                                                                           
   "equation": "DONALD + GERALD = ROBERT becomes 526485 + 197485 = 723970",     
   "valid": true                                                                
 }                                                                              
                                                                                

Approach:                                                                       

 1 Modeled each letter as getting exactly one digit (0-9)                       
 2 Enforced bijection: each digit assigned to exactly one letter                
 3 Prevented leading zeros for D, G, and R                                      
 4 Modeled column-by-column addition with carry propagation                     
 5 Used integrity constraints to enforce arithmetic correctness                 

The ASP solver found the unique solution efficiently, and the result has been   
verified to be arithmetically correct.
