Webb7 apr. 2015 · The idea is to construct a graph that is 3-colourable iff an original graph is 4-colourable. So, replace each node by a pair of nodes. Add one instance of 3 nodes, completely connected, forcing all three colours to be there, RGB. For a given XY edge, the construction will be colourable in 3 colours iff X!=Y.

Berman-Hartmanis isomorphism conjecture states that between any pair of N P -complete problems there is bijection f which is computable and invertible in polynomial-time.

It is easy to see that if U is solvable in polynomial time, then so is H. We assume that the translation module runs in polynomial time. If so, we say we have a polynomial reduction of problem H to problem U, which is denoted H P U. This is called a Karp reduction. mypoolmate.comWebb10 feb. 2024 · A Karp reduction provides a Cook reduction, since a Turing machine could decide L1 L 1 by calculating g(x) g ( x) on any input and determining whether g(x) ∈L2 g ( x) ∈ L 2.
