With the reference of this Guru Badge Winning Answer , anyone can explain what is Theta (tight bound), probably, with an example or two.
Omega is lower bound, quite understood, the minimum time an algorithm may take. And we know Big-O is for upper bound...

For example both an upper bound....
Theta requires both Big O and Omega, so that's why it's referred to as a tight bound (it must be both the upper and lower bound).
Big O is the upper bound, while Omega is the lower bound.

New digits of π will typically be CPU-bound, it's just crunching numbers.
It's pretty intuitive:
A program is CPU bound if it would go faster if the CPU were faster, i.e.

What does it mean to prove an upper bound or lower bound to an algorithm?
Answer Snippets (Read the full thread at stackoverflow):
That illustrates....
Proving a lower bound means you have proven that the algorithm will use no less than list will be sorted in one pass.
Proving an upper bound means you have proven that the algorithm will use no more than some limit on a resource.

I want to find the first item in a sorted vector that has a field less than some value x.
I need to supply a compare function that compares 'x' with the internal value in MyClass but I can't work out the function declaration.
Can't I simply overload '...

The easiest way to make the comparison work is to create a dummy .
For upper_bound and lower_bound.

For 'number-crunching' style applications that use alot of data (reads: "hundreds of MB, but not into GB" ie, it will fit nicely into memory beside the OS), does it make sense to read all your data into memory first before starting processing to avoid...

When you fix one....
There is no hard and fast rule that says it will improve performance however .
It makes sense to do things like storing your data in memory if that improves the overall performance .
Your program is as fast as whatever its bottleneck is .

For example:

Then later:
MyClass<MyClass2> myClass = new MyClass<MyClass2>();
Does this work? My coworker's hunch is no, but I can't find anything to confirm that for me and the documentation...

Super is the opossite, so you can use the bound class too.
That ClassX.isAssignableFrom(T.class)).

Given a reference to a method, is there a way to check whether the method is bound to an object or not? Can you also access the instance that it's bound to?

In either case, the new method's im_class attribute is the class from which .

What is the special case with the foreach/for loop that eliminates bounds checking? Also which bounds checking is it?

}
loop is the one that allows the JIT to safely remove array bounds checks (whether the index is within [0..length-1])
The foreach loop over arrays is equivalent to that standard for loop....
The standard
for(int i = 0; i < array.Length; i++) { .. .
