What characterizes the decision problems belonging to the class P (Polynomial Time)?
Answer
They can be solved by a deterministic Turing machine in time bounded by a polynomial function of the input size
Problems in P are those solvable efficiently, defined precisely as solvable in $O(n^k)$ time on a deterministic machine, where $k$ is fixed, making them generally considered tractable.
