Suppose that we do not know the value of the constant T, but we have the following information: the area of a circle with radius r is ar. By using this fact, write pseudocode a numerical probabilistic algorithm for finding an approximate value for 1. (" desired, you can assume that the random function returns real values.)
9. Let positive integer n be given. Of the following randomized algorithm, what is the expected value of the final value of t? Show your steps and/or justification. p:= 0 t := 0 while p < n do: t :=t+1 if random(1, 1+ 2P) # 1 then: p:= p+1
Correct answer will be upvoted else downvoted. Computer science. Phoenix loves playing with bits — explicitly, by utilizing the bitwise tasks AND, OR, and XOR. He has n integers a1,a2,… ,an, and will perform q of the accompanying questions: supplant all numbers simulated intelligence where l≤ai≤r with simulated intelligence AND x; supplant all numbers simulated intelligence where l≤ai≤r with simulated intelligence OR x; supplant all numbers man-made intelligence where l≤ai≤r with artificial intelligence XOR x; output the number of unmistakable integers artificial intelligence where l≤ai≤r. For each question, Phoenix is given l, r, and x. Note that he is thinking about the upsides of the numbers, not their files. Input The principal line contains two integers n and q (1≤n≤2⋅105; 1≤q≤105) — the number of integers and the number of inquiries, separately. The subsequent line contains n integers a1,a2,… ,an (0≤ai<220) — the integers that Phoenix begins with.…
In each of the problems below compute the average case time complexity (or expected time) of the given code. State your answer using asymptotic notation. Show your work for this problem by stating what the different cases are, the probability of each case, and how long each case takes. Also show the calculation of the expected time. a) def foo (n): #randomly choose a number between 0 and n-1 in constant time k np.random.randint (n) if k np. sqrt (n): for i in range(n): print (i) print('Never mind...') else: b) def bogosearch (numbers, target): """search by randomly guessing. numbers is an array of n numbers""" n = len (numbers) while True: #randomly choose a number between 0 and n-1 in constant time guess = np.random.randint (n) if numbers [guess] == target: return guess In this part, you may assume that the numbers are distinct and that the target is in the array. Hint: if 0 < b < 1, then 1p.bp-1 (1-b)². =

Use a mutationprobability of 0.02 and a cross-over probability of 0.5. Make separate functions for different components of thegenetic algorithm.
Correct answer will be upvoted else Multiple Downvoted. Computer science. Petya coordinated a peculiar birthday celebration. He welcomed n companions and relegated an integer ki to the I-th of them. Presently Petya might want to give a present to every one of them. In the close by shop there are m one of a kind presents accessible, the j-th present expenses cj dollars (1≤c1≤c2≤… ≤cm). It's not permitted to purchase a solitary present more than once. For the I-th companion Petya can either get them a present j≤ki, which costs cj dollars, or simply give them cki dollars straightforwardly. Assist Petya with deciding the base all out cost of facilitating his get-together. Input The originally input line contains a solitary integer t (1≤t≤103) — the number of experiments. The main line of each experiment contains two integers n and m (1≤n,m≤3⋅105) — the number of companions, and the number of interesting presents accessible. The accompanying line contains n integers…
A binary search for the word "science" over a set of 1000 documents returns results in the average search time of 100 ms. A researcher comes up with a new search method with search time of 105 ms and standard deviation (s) of 5 ms. We can conclude that the null hypothesis should be rejected and claim that the new search algorithm is better than binary search. Is True of False?
