摘要：
We present a sequential and a parallel algorithm to solve the maximum-weight independent set problem on a permutation graph. Our input data is a permutation pi = [pi1, pi2,...,pi(n)] and the weights of these vertices. our sequential algorithm takes O(n log log n) time and our parallel algorithm is of O(log2n) time and O(n3/(log n)) processors under the CREW PRAM model.
