- Given two objects x = (-1, 1, 1, -1) and y = (0, 0, 1, 0), what is the Cosine similarity between the two objects? A. B. 4 √5 C. 1 2 W|N D. 2 2 √√3 3A Locker can be opened by A and B when they are both there, as the locker has two keys, one of which is with A and other with B. C has both the keys, but he is permitted to open the locker only when B is not there. show that locker can be opened always if both A and C are there. Give boolean identify that symbolises this situation.There are 22 gloves in a drawer: 5 pairs of red gloves, 4 pairs of yellow, and 2 pairs of green. You select the gloves in the dark and can check them only after a selection has been made. What is the smallest number of gloves you need to select to have at least one matching pair in the best case? in the worst case?
- Let P(x) = "x passed the class". Let S(x) = "x studied". Let L(x) = "x got lucky". Which statement below means "Everyone who passed the class either studied or got lucky"? OVx ((P(x)→ S(x)) V L(x)) None of the other answer here listed is correct. OVx( P(x)→ S(x)) V L(x) OVx ((S(x) V L(x)) → P(x)) OV (P(x) → (S(x) v L(x)) ) OV (L(x) V (P(x) → S(x)))There are a set of courses, each of them requiring a set of disjoint time intervals. For example, a course could require the time from 9am to 11am and 2pm to 3pm and 4pm to 5pm. You want to know, given a number K, if it’s possible to take at least K courses. You can only take one course at any single point in time (i.e. any two courses you choose can’t overlap). Show that the problem is NP-complete, which means that choosing courses is indeed a difficult thing in our life. Use a reduction from the Independent set problem.There are many sensors on a wind turbine, based on each sensor's reading many alerts are generated as (start, end). For easier monitoring, our customer is asking to raise alerts on the turbine level instead of on each sensor. If any sensor is having an alert, there should be an alert for the entire wind turbine. Suppose the alerts created with two sensors readings are [(0,3),(5,10),(1,4),(10,15)], then the turbine level alert should be [(0,4),(5,15)]. Return the alerts sorted by the start timestamp. If there is no alert from the sensor level, return an empty array []. Code needs to be in Python?
- Correct answer will be upvoted else Multiple Downvoted. Computer science. Players alternate, Alice moves first. Each turn a player picks any component and eliminates it from the exhibit. In the event that Alice picks even worth, she adds it to her score. On the off chance that the picked esteem is odd, Alice's score doesn't change. Essentially, on the off chance that Bob picks odd worth, he adds it to his score. On the off chance that the picked esteem is even, Bob's score doesn't change. On the off chance that there are no numbers left in the cluster, the game finishes. The player with the most noteworthy score wins. Assuming the scores of the players are equivalent, a draw is announced. For instance, assuming n=4 and a=[5,2,7,3], the game could go as follows (there are different choices): On the principal move, Alice picks 2 and get two focuses. Her score is presently 2. The exhibit an is presently [5,7,3]. On the subsequent move, Bob picks 5 and get five…Imagine there are N teams competing in a tournament, and that each team plays each of the other teams once. If a tournament were to take place, it should be demonstrated (using an example) that every team would lose to at least one other team in the tournament.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…
- 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…G E N E T I C - A L G O R I T H M OBJECT REWARD WEIGHT A 20 1 B 5 2 C 10 3 D 40 8 E 15 7 F 25 4 G 4 5 H 7 2 Here, Maximum weight = 12 The above problem is a 0/1 Knapsack problem. 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.Mastermind is a code-breaking game for two players. In the original real-world game, one player A selects 4 pegs out of 6 colors and puts them in a certain fixed order; multiples of colors are possible (for example, red-green red-green). His opponent B does not know the colors or order but has to find out the secret code. To do so, B makes a series of guesses, each evaluated by the first player. A guess consists of an ordered set of colors which B believes is the code. The first player A evaluates the guess and feeds back to B how many positions and colors are correct. A position is correct ("black") if the guess and the secret code have the same color. Additional colors are correct ("white"), if they are in the guess and the code, but not at the same location. For example1 2 3 4secret: red-green red greenguess: red blue green purpleresults in one correct position ("black = 1") for the red peg at position one and one additional correct color ("white=1") for the green peg in the guess.…
