How to describe the extent (error band) of the clustering result(clustering center)?
I performed a k-means on a very large data, which has millions of rows and each row contains a 48-dimension vector. By applying k = 3, these data are clustered into three class, each class has a 48-dimension clustering center vector. I plot three…

How did they find Lower Bound of the following code?
procedure stars(n)
for i = 1, . . . , n do
print “∗” i many times
Question - Using the Ω-notation, lowerbound the running time of stars to show that your upperbound is in fact asymptotically tight.
Solution - Assume for simplicity that n…

Understanding Concept of Lowerbound and Upperbound in Random Number Generation?
I'm new at Java and trying to understand the concept of generating a random number within a specific range (of 500000 to 999999).
I wrote a function:
public int generateRandom(){
Random random = new Random();
return (int num =…

How to calculate Upper-Bound on Playback Buffer?
Good Afternoon,
I've tried all I can think of for the following question and rewatched the example video over 7 times. I know it involves adding the maximum buffer sizes or rates to one another, but I just cannot seem to grasp it:
Consider two…

How to set an start solution in Gurobi, when only objective function is known?
I have a minimization problem, that is modeled to be solved in Gurobi, via python.
Besides, I can calculate a "good" initial solution for the problem separately, that can be used as an upper bound for the problem.
What I want to do is to set Gurobi…

Upper bound rush hour game
I'm trying to understand the upper bound complexity for a Rush Hour game puzzle. I'm dealing with a 9x9 board, with 22 vehicles, including trucks (3 grids long) and cars (2 grids long).
By my logic, given the fact that a car can move 8 times over a…

How to use upper_bound on array of pair in C++?
I want to use upper_bound on array of pair and that too using a comparator function that compares the second parameter of pair. Please help.
Code:
bool cmp(const pair &p1, const pair &p2)
{
return p1.second

Finding lower and upper bound to complexity
I want to find lower and upper bound to complexity of this algorithm
1: for all i=1 to n*n do
2: for all j=i to 2*i do
3: output “hello world”
4: end for
5: end for
By writing it down as summation and simplifying it to
f(n) = 0.5*n^4 +…

Proving an upper bound to F(x)+G(x)
I have stumbled upon the following question:
If f(x),g(x) > 1 for every x, prove/disprove the following:
f(x)+g(x)= O(f(x)*g(x))
I dont know how to start the proof, this is very basic for my level, please help.

Find the bounds as tight as possible?
2^n −8 = O(2^n)
It says there are some positive constants c and n0 for which
0 <= f(n) <= cg(n) for all n >= n0
I solved it as:
2^n −8 <= c2^n
If c = 1, and n0 = 1
1-8 <= 1*1
-7<= 1
then for all n >= n0 it remains true.
which is true but I don't…

java: Big-Oh order of this do-while code fragment? Plus a tight upper bound
I know this is easy but my textbook doesn't talk about Big-Oh order with do-while loops, and neither do any of my other algorithm sources.
This problem states that the following code fragment is parameterized on the variable "n", and that a tight…
