Proves impossibility of constant competitiveness for k-mobile servers without request locality, gives constant lower bounds with locality, and presents a polynomial-competitive algorithm via simulation of k-page migration plus greedy moves under augmentation and locality.
In all of the following cases, we make use of ∆ψ = √ 24D ε (∑k i=1d(a′ i,c′ i)−∑k i=1d(ai,ci) ) ≤ √ 24D ε ∑k i=1d(ci,c′ i)+ √ 24D ε (∑k i=1d(a′ i,c′ i)−∑k i=1d(ai,c′ i) )
