The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1 Ex: If the input is: 7 the output is: fibonacci (7) is l3 Note: Use recursion and DO NOT use any loops.
Please write Turing machine code that computes the function f(x) = 3x. Below is an example of some Turing machine code for reference on how the code should look. this does NOT mean that this is the correct way to start the code. this is just an example of the format I need. 1,B,R,2 2,1,R,2 2,B,1,3 3,1,L,3 Assuming x = 2, the starting tape should look like this: B|1|1|B and end up like thisB|1|1|1|1|1|1|B Or if x = 3, the starting tape should look like this:B|1|1|B and end up like thisB|1|1|1|1|1|1|1|1|1|B Please do not use chatgpt for this, it does not compute the correct answer I tried a million times. I keep getting answers from tutors here that are from chatgpt and it always ends up being incorrect for Turing machine code.

Give a loop invariant that accurately relates the present values of, r, s, x, and y.Look at the GCD loop property for a hint. This invariant is also true when the calculation is between the first and second step of each iteration, in addition to being true each time the computation is at the top of the loop. Prove that your method creates and keeps the loop invariant as claimed.
Draw a state diangram for a Turing machine which, when given an input string 0", outputs 0"1". For example, if the tape contains 0000 at the beginning, then the tape should contain 00001111 when the TM halts. You may omit transitions that won't ever be taken. 4.

You are building a simulation and need to generate X ~ norm(506.5, 83.5725). Given the following U ~ unif[0,1], calculate the corresponding values of X: U = {0.8864,0.6067,0.366} Note: the following should help if you are using R. U: 0.8864, 0.6067, 0.366 Please enter your answers to four decimal places: U1= 0.8864 => X1 = U2=0.6067 => X2 = U3=0.366 => X3=
Problem Alice was given a number line containing every positive integer, x, where 1<=x<=n. She was also given m line segments, each having a left endpoint, l (1<=l<=n), a right endpoint, r (1<=r<=n), and an integer weight, w. Her task is to cover all numbers on the given number line using a subset of the line segments, such that the maximum weight among all the line segments in the chosen subset is minimal. In other words, let S=(l1,r1,w1),(l2,r2,w2),....,(lk,rk,wk), represent a set of k line segments chosen by Alice, max(w1,w2,...,wk) should be minimized. All numbers 1,2,....n should be covered by at least one of k the chosen line segments. It is okay for the chosen line segments to overlap. You program should output the minimized maximum weight in the chosen subset that covers all the numbers on the number line, or -1 if it is not possible to cover the number line. Input format The first line of the input contains an integer, n - denoting the range of numbers…
Not so. The real question states that: Construct a turing machine that computes the function ?(?) = 2?, , i.e. if the input is 0^? then the output would be 0^2? e.g. if it says 000 on the tape before the machine is run it should read 000000 on the tape when it has stopped.
Given an integer say 45, to find the sum of 45 with 8 in binary form (see the figure below), we can use the TM designed in slides 79-90 of the notes "Turing Machines and Equivalent Models I" twice to find the result. A more effective way is to design a TM to do the addition with 8 directly. 1000 101101 A + = ? Such a TM can be designed by extending the TM designed in slides 79-90 of the notes "Turing Machines and Equivalent Models I". The TM has 14 instructions and 6 states: 0, 1, 2, 3, 4, and halt. Six instructions of such a TM have been given in the first and the second tables below. Fill out the remaining blanks in the first and the second tables and also blanks in the third table to show the remaining instructions of the TM (you have to use your own text boxes here)

The same professor writes a program to analyze the chat logs from the various lectures as a partial measure of class participation. Each chat log consists of multiple lines, each of form TIME, NAME, COMMENT, in the order in which they were posted to the chat . The algorithm then sorts all that data - across all the chat logs - in order of student names, and scores each set using a metric based on the number of contributions and their length. [a] What are the various input sizes to consider when analyzing the algorithmic approaches? (One is the number of students in the class, but that is not the only factor.) [b] Which sorting algorithm do you think is best suited for the sorting portion of this algorithm and why? [c] What is the time complexity of the sorting algorithm chosen in step [b] as a function of the various input sizes identified in step [a]? [d] What is the overall time complexity of the chat analysis program as described above?
