WebA reduction is a polynomial time reduction if the output instance can be constructed in polynomial time wrt the size of the input instance. As an example a reduction from HAM to TSP takes a graph (instance of HAM) and outputs a weighted graph (weight all the edges with weight 1) and an integer (number of vertices - 1) which is an instance of TSP.

WebFor this, you need the concept of reduction. If a solution of the one NPC problem exists within the polynomial time, then the rest of the problem can also give the solution in polynomial time (but it's hard to believe).
