摘要
We show how the results of Karger, Motwani, and Sudan (1994) and Blum (1994) can be combined in a natural manner to yield a polynomial-time algorithm for (O) over tilde(n(3/14))-coloring any n-node 3-colorable graph. This improves on the previous best bound of (O) over tilde(n(1/4)) colors (Karger et al., 1994).
