Hey guys

I've been on this for while but i couldn't find any useful thing.

I want to write a function which takes O(N^4) time.

I wonder to know if there is some algorithm which has O(N^4) execution time?

It should be useful algorithm, not simply 4 for-loop which does a funny things!!!

Any suggestion will help.

Thanks in advance.

Why?
Normally, you try to work out the Omicron for an algorithm, rather than the other way around...

Still, the only one I could find was here: An O(n4) algorithm for preemptive scheduling of a single machine to minimize the number of late jobs[^] I have no idea how the heck you would test it though...
