Web1 is polynomial-time reducible to language L 2 (written L 1 P L 2) if there is a polynomial time computable function f, such that for all x, x 2L 1 if and only if f(x) 2L 2. In the previous example we showed that 3Col P CCov, and in particular, f(G) = (G;3). Note that it is easy to complement a graph in O(n2) (i.e. polynomial) time (e.g. ip 0 ... WebFeb 25, 2014 · If B is polynomial time reducible to C and C is NP-complete, then B is in NP. A problem in NP which is in NP-hard is NP-complete. Another way to show B is NP-complete is to notice that any two NP-complete problems (e.g A and C) are polynomially reducible to each other, and thus B is equivalent (two-way polynomially reducible) to any NP-complete …
