b) Resolution by refutation 18. Suppose we want to build a "Flood Prediction System" The rules we defined for our system are given below, Flood Prediction System Rule I: If there have been continuous rains from last 3 weeks Then water level in water reservoirs is above its dangerous level Rule II: If there is prediction of rains in for next 4 weeks AND water level in water reservoirs is above its dangerous level Then there are chances of over flooding in rivers. Rule III: If there is prediction of heavy clouds for coming four weeks AND there is prediction of coming air with heavy concentration of water Then there is prediction of rains in for next 4 weeks uppose we have been given the following facts There have been continuous rains from last 3 weeks and in coming four weeks there are chances of coming air with heavy concentration of water along with heavy clouds. Prove that there are chances of over flooding in rivers using forward as well as backward chaining. b) Resolution by refutation 18.
