We consider the Minimum Linear Arrangement problem and the (Uniform) Sparsest Cut problem. So far, these two notorious NP-hard graph problems have resisted all attempts to prove in...
The Positive-Negative Partial Set Cover problem is introduced and its complexity, especially the hardness-of-approximation, is studied. The problem generalizes the Set Cover probl...
Peer-to-peer systems are positioned to take advantage of gains in network bandwidth, storage capacity, and computational resources to provide long-term durable storage infrastruct...
Abstract. As the speed gap between CPU and memory widens, memory hierarchy has become the performance bottleneck for most applications because of both the high latency and low band...
Traditionally, the development of computing systems has been focused on performance improvements driven by the demand of applications from consumer, scientific, and business domai...
