are both hierarchical.Configuration leverages classification’s notion of prototype concepts.Configuration suggests starting with a prototype concept and assigning values to variables.Chair Legscount :

configured for similar problems with differing constraints.Image credit:https://commons.wikimedia.org/wiki/File:Chair_4a.jpg27Assignment How would you use configuration to design an agent that could
