          <dc:subject>maximizing minimum load</dc:subject>
          <dc:description>We consider the problem of maximizing the minimum load for&#13;
machines that are controlled by selfish agents, who are only&#13;
interested in maximizing their own profit. Unlike the classical&#13;
load balancing problem, this problem &#13;
has not been considered for selfish agents until now.&#13;
&#13;
For a constant number of machines, $m$, we show a&#13;
monotone polynomial time approximation scheme (PTAS) with running&#13;
time that is linear in the number of jobs. It uses a new&#13;
technique for reducing the number of jobs while remaining close&#13;
to the optimal solution. We also present an FPTAS for the classical&#13;
machine covering problem, i.e., where no selfish agents are involved&#13;
(the previous best result for this case was a PTAS)&#13;
and use this to give a monotone FPTAS.&#13;
&#13;
Additionally, we give a monotone approximation algorithm with&#13;
approximation ratio $min(m,(2+eps)s_1/s_m)$ where $eps&gt;0$ can&#13;
be chosen arbitrarily small and $s_i$ is the (real) speed of&#13;
machine $i$. Finally we give improved results for two machines.</dc:description>
