Forward Chaining| 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 viremia. Working Memory: runny nose temperature = 101.7 headache cough Write all the steps involved in forward chaining given the above facts and rules. What conclusion can you come to for this person (ies, 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
