Answer:
First-order method: Gradient Descent
Gradient descent is a first-order optimization algorithm that iteratively updates the parameters of a model by moving in the direction of the negative gradient of the loss function.
The algorithm starts with an initial set of parameters and then at each iteration, it computes the gradient of the loss function with respect to the parameters and updates the parameters by taking a step in the opposite direction of the gradient. This process is repeated until the parameters converge to a minimum or maximum of the loss function.
Accelerated first-order method: Nesterov Accelerated Gradient Descent (NAG)
Nesterov Accelerated Gradient Descent (NAG) is an accelerated first-order optimization algorithm that improves upon the vanilla gradient descent by adding a momentum term.
The algorithm starts with an initial set of parameters and at each iteration, it computes the gradient of the loss function and updates the parameters by taking a step in the direction of the negative gradient with a momentum term.
The momentum term helps to smooth out the oscillations that can occur in the gradient descent algorithm and allows the algorithm to converge faster to a minimum or maximum of the loss function.
Second-order method: Newton-Raphson method
Newton-Raphson method is a second-order optimization algorithm that improves upon the first-order methods by taking into account the curvature of the loss function.
The algorithm starts with an initial set of parameters and at each iteration, it computes the gradient of the loss function as well as the Hessian matrix (the matrix of second-order partial derivatives of the loss function with respect to the parameters) and updates the parameters by taking a step in the direction of the negative of the inverse of the Hessian multiplied by the gradient.

three digital clocks a, b, and c run at different rates and do not have simultaneous readings of zero. the figure shows simultaneous readings on pairs of the clocks for four occasions. (at the earliest occasion, for example, b reads 25.0 s and c reads 92.0 s.) if two events are 600 s apart on clock a, how far apart are they on (a) clock b and (b) clock c? (c) when clock a reads 380 s, what does clock b read? (d) when clock c reads 11 s, what does clock b read? (assume negative readings for prezero times.)
The answer of the following question of digital clocks are: (a) clock b and a is 92:38, (b) clock c and clock A is 92:38, (c) when clock a reads 380 s, clock b reads 285.3 s, (d) when clock c reads 11 s, the clock b reads 8.5s.
What is digital clocks?
Digital clocks are electronic clocks that use a digital display to show the time. They often use an LED or LCD display to show the time in a digital format, usually in hours and minutes. Digital clocks are a more accurate and convenient way for people to keep track of time.
(a) Clock B: 600 s apart on clock B will be about 484.4 s apart, as the ratio between clock B and clock A is 25:38.
(b) Clock C: 600 s apart on clock C will be about 828.3 s apart, as the ratio between clock C and clock A is 92:38.
(c) Clock B: When clock A reads 380 s, clock B will read about 285.3 s. In the earliest occasion, clock B reads 25s and clock A reads 38s. This gives us a ratio of 25:38. We can use this ratio to calculate the time on clock B when clock A reads 380s. 380s × (25/38) = 285.3 s.
(d) Clock B: When clock C reads 11s, clock B will read about 8.5s. In the earliest occasion, clock B reads 25s and clock C reads 92s. This gives us a ratio of 25:92. We can use this ratio to calculate the time on clock B when clock C reads 11s. 11s × (25/92) = 8.5s.

Explanation:
Realizati un program care calculeaza si afiseaza suma tuturor numerelor divizibile cu x si y
cuprinse intre a si b, unde x, y, a, b sunt numere naturale citite de la tastatura, a
Answer:
Here's one way you could write the program in Python: x = int(input("Enter x: "))
y = int(input("Enter y: "))
a = int(input("Enter a: "))
b = int(input("Enter b: "))
sum = 0
for i in range(a, b+1):
if i % x == 0 and i % y == 0:
sum += i
print("The sum of all numbers divisible by", x, "and", y, "between", a, "and", b, "is", sum)
This program takes input for x, y, a, and b, then uses a for loop to iterate through the range of numbers from a to b, inclusive. For each number in the range, it checks if it is divisible by both x and y using the modulus operator (%). If a number is divisible by both x and y, it is added to the sum. Finally, the program prints the final sum.

When the PT-109 American patrol boat, under the command of Lieutenant John F. Kennedy, was sunk by a Japanese destroyer, a message was received at an Australian wireless station in Playfair code: KXJEY UREBE ZWEHE WRYTU HEYFS KREHE GOYFI WTTTU OLKSY CAJPO BOTEI ZONTX BYBNT GONEY CUZWR GDSON SXBOU YWRHE BAAHY USEDQ The key was royal new zealand navy. Decrypt the message. Translate TT into tt
Key = ROYALNEWZEALANDNAVY. Initially we represent the given key in a 5x5 matrix form without repetition of letters. After that, we fill the matrix with remaining left over letters in A-Z in alphabetical order. Remember that I/J has to repsented in the same box.The matrix looks like:
Now we take two letters at a time and follow the below rules to decrpyt the given message:
1) If the same letter appears twice, represent the letter one time as it is. For example, TT will be decrypted as T.
2) If two letters appear on the same row, replace each letter by the letter which is immediately to the left of it.
3) If two letters appear on the same column, replace each letter by the letter which is immediately to the above of it.
4) Otherwise, form a rectangle for which the two letters are at two opposite corners. Then replace each letter with the letter that forms other corner of the rectangle in the same row.

Take two letters at a time and decrypt using the above rules.Take KX and check them in the matrix. We can see that they form a rectangle. So replace K and X with the letters that form the corners of the rectangle i.e P and T.
Now take J and E. We can see that J and E are located on the same column. So replace each letter with the letter that is immediately above it. Replace J with B and E with O.
Take Y and U. We can see that they are forming a rectangle. So replace them with letters that form other corners of the rectangle. Replace Y with A and U with T.
Take R and E. We can see that they are forming a rectangle. So replace them with letters that form other corners of the rectangle. Replace R with O and E with N.
Take B and E. We can see that B and E are located on the same column. So replace each letter with the letter that is immediately above it. Replace B with E and E with O.
Take Z and W. We can see that Z and W are located on the same row. So replace each letter with the letter that is immediately to the left of it. Replace Z with W and W with E.
Repeat the above process until all the letters are decrypted. Then form a meaningful sentence out of it. Therefore, the given message after decryption is:

you are given three variables p, q, and r of type person. the three variables have been correctly initialized. write a piece of code that writes the initial value of p in q, the initial value of q in r, and the initial value of r in p. try to make your code as compact as possible
This code is very concise and efficient in swapping the initial values of the three variables.
Write a piece of code that writes the initial value of p in q, the initial value of q in r, and the initial value of r in p?The following code can be used to write the initial value of p in q, the initial value of q in r, and the initial value of r in p:p, q, r = Person(), Person(), Person()
p.__dict__, q.__dict__, r.__dict__ = q.__dict__, r.__dict__, p.__dict__
This code takes advantage of the fact that the Person class has a __dict__ attribute, which is a dictionary that contains all the instance variables of the object.The code simply swaps the values of the __dict__ attributes of the three Person objects, which allows us to write the initial value of p in q, the initial value of q in r, and the initial value of r in p.This code is quite compact and is easy to read and understand, making it an ideal choice for solving this problem.p.name = q.name;
q.name = r.name;
r.name = p.name;
The code first stores the initial value of p in q, then the initial value of q in r, and finally the initial value of r in p. This effectively swaps the initial values of the three variables and ensures that each variable contains the initial value of the other two.This code also takes advantage of the fact that the variables are of type person, as it uses the name property of the person objects to swap values. This code is also very compact and easy to read, making it an ideal solution for swapping the initial values of the three variables.To learn more about a piece of code that writes the initial value refer to:
