What is POLYNOMIAL TIME COMPLEXITY?
The concept of polynomial time leads to several complexity classes in computational complexity theory. Some important classes defined using polynomial time are the following. P: The complexity class of decision problems that can be solved on a deterministic Turing machine in polynomial time.
