Consider a set of natural language sentences collected from Web pages. A human can like another human. A human can have a sex property of a man or a woman. A man can be the father of another human. A woman can be the mother of another human. A human can be married to another human. A human can have a BirthYear property of type “xs:Year”. If a human is married to another, then they like each other. viii. If a human is a mother or father, the human is a parent. Write a RDF schema and give a graphical presentation to describe these relationships.

Consider all words representing the sound a cow makes to be the following infinite set: "moo!", "mooo!", "moooo!", etc. Show a regular expression that would accept any line in which the sound a cow makes occurs at least two times (they don't have to be consecutive or identical). Each instance must be preceded by a non-letter or occur at the start of a line. It does not matter what occurs after the explanation points.
Let p, q, and r be the propositions p: You started a new video game this week. q: You finished all its quests.r: You didn’t win the platinum trophy.Express each of these propositions as an English sentence.¬p → ¬q(p ∧ q) → (¬r)((¬p) → (¬q)) ∨ (q → (¬r))(p ∧ q) ∨ (¬q ∧ r)
Let D be a set of dogs including the particular dogs Cardie (c) and Duncan (d). Define the following predicates on D: W(x) means "dog a likes walks", T(x) means “dog æ is a terrier", R(x) means "dog x is a Rottweiler", and S(x, y) means "dog a is smaller than dog y" or equivalently “dog y is larger than dog r". Using the first five of the statements below, prove the last statement using quantifier rules. (Translate the statements into symbolic ones before you start.) • Duncan is a terrier. • All terriers are smaller than Cardie. • Cardie is smaller than some Rottweiler. • If a first dog is smaller than a second dog, and the second is smaller than a third dog, then the first dog is smaller than the third. • All dogs like walks. • There is a Rottweiler who is larger than some terrier who likes walks.

Can you help me with this code because this is a little difficult for me:question that i need help with:The Lights Out puzzle consists of an m x n grid of lights, each of which has two states: on and off. The goal of the puzzle is to turn all the lights off, with the caveat that whenever a light is toggled, its neighbors above, below, to the left, and to the right will be toggled as well. If a light along the edge of the board is toggled, then fewer than four other lights will be affected, as the missing neighbors will beignored. In this section, you will investigate the behavior of Lights Out puzzles of various sizes by implementing a LightsOutPuzzle class task: A natural representation for this puzzle is a two-dimensional list of Boolean values, where True corresponds to the on state and False corresponds to the off state. In the LightsOutPuzzle class, write an initialization method __init__(self, board) that stores an input board of this form for future use. Also write a method…
2. Consider the following information: - Animals can outrun any animals that they can eat. Carnivores eat other animals. - Outrunning is transitive: if x can outrun y and y can outrun z, then x can outrun z. Lions eat zebras. Zebras can outrun dogs. Dogs are carnivores. Using this a. Write a set of FOL sentences representing the information using the standard notation for FOL. b. Convert these sentences to clausal normal form. c. Use resolution theorem proving to find three animals that lions can outrun, showing the result as a proof graph.
Suppose a person can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. A person can redeem 3 coupons for one chocolate bar from the machine. This means that once a person has started buying chocolate bars from the machine, he/she always has some coupons. A person would like to know how many chocolate bars can be bought, if a person starts with N dollars and always redeem coupons, if he/she has enough for an additional chocolate bar. For example: With 3 dollars a person could buy 4 chocolate bars after purchasing 3 bars giving him/her 3 coupons and then redeeming the 3 coupons for one bar. This would leave him/her with one extra coupon. Thus, will have 4 chocolate bars and still have one coupon leftover. For 11 dollars, a person can have 16 chocolate bars and still have one coupon leftover. For 12 dollars, a person can have 17 chocolate bars and have two coupons leftover. Write a complete Python program that prompts a buyer to input…

You have to carry the different objects in your bag in a way such that the reward is maximized without exceeding the weight limit. You can carry an object exactly once but you always have to carry the object labeled “H”. Encode the problem and create an initial population of 4 different chromosomes. Explain what would be an appropriate fitness function for this problem. Use the fitness function and perform natural selection to choose the 2 fittest chromosomes. Using the selected chromosomes perform a single point crossover to get 2 offspring. Perform mutation and check the fitness of the final offspring. Explain your work.
Please help me Josephus Problem is a theoretical problem related to a certain counting-out game. On thiscase, people are standing in a circle waiting to be executed. After a specified number ofpeople are skipped, the next person is executed. The procedure is repeated with theremaining people, starting with the next person, going in the same direction and skippingthe same number of people, until one person remains, and is freed.Arrange the numbers 1 , 2, 3 , ... consecutively (say, clockwise) in a circle. Now removenumber 2 and proceed clockwise by removing every other number, among those thatremain, until one number is left. (a) Let denote the final number which remains. Find formula for .(b) If there are 70 people, what is the safe number (the number that remains)?
The domain is the set {a, b, c, d, e}. The table below shows the value of two predicates for each of the elements in the domain.
