In this paper we show that an optimal vertex ranking of a permutation graph can be computed in time O(n6), where n is the number of vertices. The demonstrated minimal separator approach can also be used for designing polynomial time algorithms computing an optimal vertex ranking on the following classes of well-structured graphs: circular permutation graphs, interval graphs, circular arc graphs, trapezoid graphs and cocomparability graphs of bounded dimension.
