Approximation schemes for scheduling on parallel machines

By Noga Alon, Yossi Azar, Gerhard J. Woeginger and Tal Yadid


We discuss scheduling problems with m identical machines and n jobs where each job has to be assigned to some machine. The goal is to optimize objective functions that solely depend on the machine completion times. As a main result, we identify some conditions on the objective function, under which the resulting scheduling problems possess a polynomial time approximation scheme. Our result contains, generalizes, improves, simplifies, and unifies many other results in this area in a natural way

Topics: Scheduling theory, approximation algorithm, approximation scheme, worst case
