Abstract
A graph G = ( V, E ) is said to be ( k, δ ) almost colorable if there is a subset of vertices V ′ ⊆ V of size at least (1 − δ ) | V | such that the induced subgraph of G on V ′ is k -colorable. We prove that for all k , there exists δ > 0 such for all ε > 0, given a graph G it is NP-hard (under randomized reductions) to distinguish between:
