- Q9: Knowledge Representation - Consider the following statements: 1. All children have a favourite toy. 2. Whoever likes dolls or soft toys is a child. 3. Fuzzy is a soft toy: SOFT-TOY (Fuzzy). 4. Ellen likes Fuzzy: LIKES (Ellen, Fuzzy). (a) Using only the following predicates CHILD(*), HAS-FAV-TOY(*), LIKES (*,*), DOLL(*) and SOFT-TOY(*), represent the two statements as predicate calculus well formed formulas (wffs). Notes: The asterisks indicate the number of arguments in each predicate; keep your representation consistent with the predicates in statements 3 and 4 above.) (b) Convert these statements into clauses. (c) Use resolution refutation to prove that Ellen has a favourite toy. State the goal, and indicate clearly the number of the clause you are using, and any substitutions you make. Goal 5: HAS-FAV-TOY(Ellen). Negated goal: ¬HAS-FAV-TOY(Ellen).6. if (roll_no%2%3D%3D0) return left_row; else return right_row; Represent above construct in lambda calculus. Derive any predicates, construets and data types that you need.Material : Fuzzy Logic As a member of an excellent engineering team, you and the team are asked to design a futuristic car capable of automatically controlling the speed of the car based on the variable linguistic inputs such as temperature and weather (cloud-cover). Now, given three variable linguistics namely: temp = (freezing, cool, warm, hot); cloud-cover = (sunny, partly, overcast); speed = (slow, fast) With each of membership function is as follows (See First Picture): Determine what is the speed of the car if the variable input temp=55oF and the cloudcover = 35% with fuzzy inference rules applied are: If cloud_cover = sunny & temp = warm → speed = fast If cloud_cover = cloudy & temp = cool → speed = slow

- Suppose that: • variable X can represent any creature, • the predicate tove(X) is true if and only if X is a tove, • the predicate slithy(X) is true if and only if X is slithy, and • the function action(X) is a function that returns the kind of action that X is able to perform. Write a statement in predicate logic with the following meaning: "Any tove that can gyre or gimble must also be slithy." The following symbols are provided for you to copy if you wish (though not many of them are needed in this question, and you are not limited to using only the symbols that are listed here): 3 V A V ¬ A → € e ± Answer:Every if construct begins with if and must be terminated with .a. endb. endifc. stopd. fiCreate a filtering iterator with a static select function that accepts a basic iterator and an object (referred to as the predicate).
