Abstract

We present a mathematical justification of the technique of force-directed scheduling and propose two modifications of the basis algorithm introduced by Paulin and Knight. The newly presented modifications improve the effectiveness of force-directed scheduling without affecting its time complexity. This is illustrated by an empirical performance analysis based on a number of problem instances.
