If there are m open shops, our algorithm has a worst case ratio of 2. If only two open shops are valid, it can be improved to 32.
Compared with several 2-approximation algorithms in the literature, this paper presents an approximation algorithm with a worst case ratio 2−2m+1<2 for any m QCs.
For an arbitrary speed ratio s ≥ 1, an approximation algorithm with worst case ratio (1+s)21+s+s2 is provided.
Our measure of efficiency is defined as the worst case ratio of the total utility of a utility proportional fair rate vector and the maximum possible total utility.
If the reduce tasks are preemptive, we provide an approximation algorithm with worst case ratio of 2. On online version where jobs arriving over time, we design two heuristics for non-preemptive and preemptive reduce tasks respectively.
On offline version, if the reduce tasks are non-preemptive, we design an approximation algorithm whose worst case ratio is at most max{1+Δ2−1n,Δ}, where Δ= v1vn is the ratio of the fastest speed to the slowest speed.
