WebSo for example we could use a polynomial number of instances of Y and we could do lots of transformations, as long as none of the costs can be exponential in any situation. But we get pretty far just with this simple concept of reduction. Important point about polynomial time reduction is that it's transitive. WebNov 11, 2024 · A polinomial time reduction from a problem A to problem B is a polynomial function f: I_A → I*_B, where I_A is the set of all instances of problem A and I*_B is a subset of the instances of ... csn regency waterloo
What is polynomial-time reduction? - Quora
In computational complexity theory, a polynomial-time reduction is a method for solving one problem using another. One shows that if a hypothetical subroutine solving the second problem exists, then the first problem can be solved by transforming or reducing it to inputs for the second problem and calling the subroutine one or more times. If both the time required to transform the first problem to the second, and the number of times the subroutine is called is polynomial, then … WebNov 1, 2013 · 1 Answer. Sorted by: 1.
