The authors present parallel algorithms for recognizing the chordal graphs and k trees. Under the model of computation PRAM with concurrent reading and writing allowed, these algorithms take O(log n) time and require O(n/sup 4/) processors. The authors' algorithms have an improved processor-bound than an independent result by Edenbrandt for recognizing chordal graphs in parallel using O(n/sup 3/m) processors. Furthermore, their characterizations for chordal graphs and kappa trees are interesting in their own right.
