An additive spanner of an unweighted undirected graph G with distortion d is a subgraph H such that for any two vertices u, v ∈ G, we have δH(u, v) ≤ δG(u, v) + d. For every...
We present lower bounds on the computational power of an optical model of computation called the C2-CSM. We show that C2-CSM time is at least as powerful as sequential space, thus ...
In this paper we present a novel and fast estimation technique that produces tight latency lower bounds for Data Flow Graphs representing time critical segments of the application...
Abstract. Highly nonlinear Boolean functions occupy an important position in the design of secure block as well as stream ciphers. This paper proves two new lower bounds on the non...
