: Bonus not a must: Assume KB consists of the following rules:
R: Sodax Chipsy: Bonus not a must: Assume KB consists of the following rules:
R: Sodax Chipsy Cheaperx y
R: Chipsx Cerealsy Cheaperx y
R: Cheaperx y Cheapery z Cheaperx z
And the facts:
F: SodaSprite
F: ChipsRuffles
F: CerealsCheerios
F: CerealsMiniWheats
Assume that all facts FF are known at the beginning of the inference process. Illustrate the process of forward chaining by listing all newly inferred facts. Assume that both rules and facts are matched and tried in the order of their appearance.
