"WebAug 17, 2024 · The existence of a reduction algorithm from A to B will imply the following, 1. If B ∈ P, then A ∈ P (You can just reduce from A to B in polynomial time and solve B in polynomial time. Combining this gives polynomial time algorithm for A) 2. If B ∈ NP, then A ∈ NP. 3. If A is NP-hard, then B is NP-hard. " - Polynomial-time reduction
