- Please answer the question 4, 5, 6arrow_forwardSuppose 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:arrow_forwardTanslate each of these statements into logical expressions using predicates, quan-tifiers, and logical connectives.

- I will thumbs up if you answer all. please convert FOL to CNF Convert each of the following English statements into a single first-order logic sentence using the following constants and predicates. •Constants: Apples, Oranges, Chess, Go, John, Mary. •Predicates: oLikes(x,y): person x likes food y oPlays(x,y): person x plays game y a.If a personlikesApples, then they play chess. b.If a person likesOranges, then they play Go. c.A person likesApples or Oranges, but not both. d.John likes apples. e.Mary does not like anything that John likes. and then: Convert each of the first-order logic sentences in Problem 2to conjunctive normal form (CNF). There is no need to show intermediate steps.

Write a Prolog preciate schedule(S) that is true if S is a valid schedule. A schedule lists the fixtures for each day of the competition. In a fixture (A,B), team A is the home team and team B is the away team. A schedule is valid if: • there are no more than three matches on any day, • each team has the same number of home and away fixtures in the whole schedule, and • each team has at least four rest days between fixtures. Ideally the schedule S should be as short as possible, and the predicate schedule should be able to generate multiple valid schedules.arrow_forward
