How to solve: T (n) = T (n/2) + T (n/4) + T (n/8) + (n)
I know how to do recurrence relations for algorithms that only call itself once, but I'm not sure how to do something that calls itself multiple times in one occurrence. For example: T(n) = T(n/2...
algorithm - Solve: T (n) = T (n-1) + n - Stack Overflow
In Cormen's Introduction to Algorithm's book, I'm attempting to work the following problem: Show that the solution to the recurrence relation T(n) = T(n-1) + n is O(n2 ) using substitution (Ther...
How to make sklearn.metrics.confusion_matrix() to always return TP, TN ...
15 I am using sklearn.metrics.confusion_matrix(y_actual, y_predict) to extract tn, fp, fn, tp and most of the time it works perfectly.
Confusion matrix for values labeled as TP, TN, FP, FN
I can aggregate these values into total number of TP, TN, FP, FN. However, I would like to display a confusion matrix similar to the one generated by using the folowing:
Complexity of the recursion: T (n) = T (n-1) + T (n-2) + C
If you were also interested in finding an explicit formula for T(n) this may help. We know that T(1) = c and T(2) = 2c and T(n) = T(n-1) + T(n-2) + c. So just write T(n) and start expanding. T(n) = T(n-1) + T(n-2) + c T(n) = 2*T(n-2) + T(n-3) + 2c T(n) = 3*T(n-3) + 2*T(n-4) + 4c T(n) = 5*T(n-4) + 3*T(n-5) + 7c and so on. You see the coefficients are Fibonacci numbers themselves! Call F(n) the ...

What does the notation T(n) mean? - Stack Overflow
From wikipedia article on O-notation: "A function T (n) that will express how long the algorithm will take to run (in some arbitrary measurement of time) in terms of the number of elements in the input set."
Easy: Solve T (n)=T (n-1)+n by Iteration Method - Stack Overflow
Can someone please help me with this ? Use iteration method to solve it. T(n) = T(n-1) +n Explanation of steps would be greatly appreciated.
algorithm - Solving T (n) = 4T (n/2)+n² - Stack Overflow
I am trying to solve a recurrence using substitution method. The recurrence relation is: T (n) = 4T (n/2)+n 2 My guess is T (n) is Θ (nlogn) (and i am sure about it because of master theorem), and to find an upper bound, I use induction. I tried to show that T (n)<=cn 2 logn, but that did not work. I got T (n)<=cn 2 logn+n 2. Then I tried to show that, if T (n)<=c 1 n 2 logn-c 2 n 2, then it ...
Calculating the Recurrence Relation T (n)=T (n-1)+logn
We are to solve the recurrence relation through repeating substitution: T(n)=T(n-1)+logn I started the substitution and got the following. T(n)=T(n-2)+log(n)+log(n-1) By logarithm product rule, l...
