Speed Scaling for Energy and Performance with Instantaneous Parallelism
Abstract. We consider energy-performance tradeoff for scheduling parallel jobs on multiprocessors using dynamic speed scaling. The objective is to minimize the sum of energy consu...

3-hitting set on Bounded Degree Hypergraphs: Upper and Lower Bounds on the Kernel Size
We study upper and lower bounds on the kernel size for the 3-hitting set problem on hypergraphs of degree at most 3, denoted 33-hs. We first show that, unless P=NP, 3-3-hs on 3-un...
