   i want to design an algorithm using A* and Hill climbing alghorithms:   
      
   problem:   
      
   we have 2 agents in helix 4*4, both mobile and first agent is   
   following second agent. Authorized movements for agents is right,   
   left, up and down. agents can walk 1that towards must determined by 2   
   mentioned strategies. Both agents have to be moved at any step.   
      
      
   For hill climbing, consider a Heuristic function and once regardless   
   if this function implementation
