 Abstract: We consider a generalized 2-server problem on the uniform space in which servers have different costs. Previous work focused on the case where the ratio between these costs was very large. We give results for varying ratios. For ratios below 2.2, we present an optimal algorithm which is trackless. %Furthermore, our algorithm is trackless, %which means that it is restricted from storing %explicitly points from the metric space. We present a general lower bound for trackless algorithms depending on the cost ratio, proving that our algorithm is the optimal trackless algorithm up to a constant factor for any cost ratio. The results are extended for the case where we have two sets of servers with different costs.
