What is the fastest known sort algorithm for absolute worst case? I don't care about best case and am assuming a gigantic data set if that even matters.

O(nlog n) mean case, O(n^2) in the worst case an "absolute fastest" assuming a worst case scenario because different sorts have different worst with good worst ....
Assuming randomly sorted data, quicksort.

Can someone please explain to me how one can determine the worst-case complexity of an algorithm. I know that the we need to use the equation W(n) = max{t(I)|I element of D), where D is the set of inputs of size n. Do I calculate the number of operations...

Are talking about worst case, you are usually talking about non deterministic algorithms, where you might have; n;j++){ if(rand() > .5) j = n; } }
We would say that the worst-case is O(n^2).

Out of curiosity, what is ListBox.FindString(string)'s worst case runtime? MSDN does not state this in its API docs.
I have a strong suspicion it is O(n), I have a sorted list and O(log n) or O(1) would be nice, is there a way to change which sorting ...

Obviously that is O(n) in the worst-case (i.e.
I don't want to paste here just in case it violates MS's license), it's clear the method is O(n) worst).

Hi every one. I have this question, and I don't know how to solve it, because I don't understand it. :(
The question is:
Programs A and B are analyzed and are found to have worst case running times no greater than 150 n log n and n 2 , respectively. Answer...

Worst case run time means the absolute longest the program will run given an input of length n.
And figuring out which is larger in each case.

The Java memory model makes it clear what can and cannot be assumed about how threads interact through memory. For example, if one thread writes a new value to a field without appropriate synchronization then the new value is not guaranteed to be observable...

(Your application probably won't work at all) ;).
For worst case JVM, try a mobile phone.
Of any VM which guarantees worst case behavior all the time, which seems to be what you are asking appear in 5/6.

I am trying Bubble sort. There are 5 elements and array is unsorted. Worst case for bubble sort shuold be O(n^2).
As an exmaple I am using
A = {5, 4, 3, 2, 1}
In this case the comparison should be 5^2 = 25. Using manual verification and code, I am getting...

If you in the worst case.
As many elements, you can expect it to take (worst case) 4-times as long (as an upper bound).

Best case = 11-0

Answer Snippets (Read the full thread at stackoverflow):
The worse case running time is a function of the maximum depth of the directory.
I'd say it's O(N, it's just bookkeeping.
Complexity, since you're trying to calculate worst-case running time.

In the worst-case scenario, the core melts through the bottom of the reactor vessel and falls onto the floor of the quake.
