We present a new proof of a theorem of Erd˝ os, Rubin, and Taylor, which states that the list chromatic number (or choice number) of a connected, simple graph that is neither complete nor an odd cycle does not exceed its maximum degree ∆. Our proof yields the first-known linear-time algorithm to ∆-list-color graphs satisfying the hypothesis of the theorem.(More)
