6) Forward Chaining (10 marks = 7+3] i) The following is our knowledge base: Rule 1: if nasal congestion and vicemia, then diagnose influenza. Rule 2: If runny nose, then nasal congestion. Rule 3: If body aches, then achiness. Rule 4: If temperature greater than 100, then fever. Rule 5: If headache, then achiness. Rule 6: if fever and achiness and cough, then vicemia, Working Memory: Cunny nose temrecatus 101.7 beadache souh write all the steps involved in forward chaining given the above facts and rules. What conclusion can you come to for this person (i.e., who has a runny nose, headache, cough, etc.)? | ii) Did we use Degree Heuristic as a substitute for MRV (Minimum Remaining values) when we tried to improve the efficiency of the backtracking algorithm for map coloring
