Cover Problem

This paper studies the combination problem of parallel machine scheduling and the vertex cover problem. Wang and Cui developed a [Formula: see text]-approximation algorithm for this problem [13], where [Formula: see text] is the number of parallel machines. We reduce the approximation factors from [Formula: see text] to [Formula: see text] for [Formula: see text], from [Formula: see text] to [Formula: see text] for [Formula: see text], and to [Formula: see text] for [Formula: see text].
