摘要
In the paper "The complexity of mean flow time scheduling problems with release times", by Baptiste, Brucker, Chrobak, Durr, Kravchenko and Sourd, the authors claimed to prove strong -hardness of the scheduling problem , namely multiprocessor preemptive scheduling where the objective is to minimize the mean flow time. We point out a serious error in their proof and give a new proof of strong -hardness for this problem.
