In this paper, we present a linear time algorithm for substitution decomposition on chordal graphs. Based on this result, we develop a linear time algorithm for transitive orientation on chordal comparability graphs. Which reduces the complexity of chordal comparability recognition from O(n2) to O(n+m). We also devise a simple linear time algorithm for interval graph recognition where no complicated data structure is involved.
