"WebPolynomial time reductions and transformations In practice, when we are reducing one NP problem to another NP problem, it will be a polynomial time transformation. We will use the same notation p to denote a polynomial time reduction and polynomial time transformation. As we have observed before if L 1 p L 2 and L 2 2P, then L 1 2P.
