Understanding Polynomial-Time Reduction in NP-Hard and NP-Complete Problems

Here we introduce a "polynomial-time reduction," which is one in which takes polynomial time (obviously). We also introduce the notion of NP-hardness and NP-completeness. We then show that if a problem is NP-complete, and is also in P, then P = NP.
