Abstract
We characterize interval graphs in terms of a certain linear order on their vertex set. It turns out that with this linear order, the well-known greedy heuristic “always use the smallest available color” yields an exact coloring algorithm for interval graphs. In addition, the heuristic can be implemented to run in linear time.
