摘要

We consider a multi-agent scheduling problem on a single machine with k competing agents. The objective is to minimize the total completion time of first agent, subject to the condition that the total completion time of any other agent is bounded. When k is arbitrary, the exact complexity of this problem is open. We show the unary NP-hardness of this problem and present a polynomial-time algorithm when all the jobs of first agent have deadlines and any other agent has only one job.
